I finally got to run my car opened exhaust this weekend..(alot of work)..I was rewarded with 3 tenths and 2 MPH..MY previus best had been a 11.50 @119MPH on a 1.59 60ft....Opened up this weekend i went a 11.23 @121.76 on a 1.560ft..ON BFG DRAG RADIALS...wew wee.lol..

What computer do you have?? Tuning? Are those Hooker shorty headers any good???

11SEC91Z

iTrader: (4)

I still have the stock GM computer in my car with a Level5 TPIS chip.Ive Been extremely lucky with my combo,because believe it or not i still have stock injectors and stock fuel pump the hooker shorty headers are ok.(good for tourqe) I need to switch to Hooker Super Comps really bad<but im having a roll bar delima.Im not sure if i want to put one in my car<and i know when i put the new headers on the car will probably run 11.20s closed up on street tires.The only reason i had opened it up is because me and some friends rented out one lane at Maryland International Raceway and we could run what we wanted too so i got to open her up..She liked it.lol

You did almost 122 mph!!! You are close to 10s NA!! How does that zzx idle?? Why was it alot of work to open your exhaust??

Track times correct?? Not g-tech? Corrected?? Could you please go into detail about your internal engine parts, and the weight of your car. What porting do you have on your heads??

Guido

Id like to know the answer to this one too.

Last year I had a 406, mini ram, AFR190's, 230/236 cam, slicks, all forged rotating assembly, speed pro and a VORTECH SUPERCHARGER. Granted my belt was slipping and I was getting 4-8psi at any given time but I only ran 11.28 @ 120.6 with a 1.57 60'.

Id love to know more about this combo. Your car must weigh 2600 pounds or something...

11SEC91Z

iTrader: (4)

Full weight..Except for dragstars..Act 3500 stall..373 gears..This is a TPIS built 383.Look at the catalog..you will see all the (expensive parts)lol .AFR 195 cc heads 2.02 valves..ZZX cam.. the exhaust is hard to open because it still has the dual cat setup on it..these are track times im not a GPS believer..thats it fellas

Guido

JFC I just went and looked at their website and its worse now then it was before! I hate flash .

I didnt find any 383's on there either.

Just sounds far fetched to me. Did they tune the car for you at their shop or something? I mean, I suppose it is possible but damn that is just out there... Ill let them tune my car. If they can tune your NA 383 to run bottom 11's they should be able to tune my turbocharged 406 to upper 8's.

GofasterFirebird

iTrader: (3)

Ok, I spoke with him online. I also looked at the tpis catalogue and they do sell a 383 rotating assembly. Afr 195 he said slight exhaust port. Stock injectors?? Pump?? He claims to have video yet it is on VHS. Calling BS Guido?

rhuarc30

Not so out there guido, my firebird runs the same kinda times NA. On the other hand it's a 406 with afr 210's, mini-ram, and solid roller cam. TPiS does sell complete engines, they're a division of Cottrel Racing engines, pricey though. It's in their printed catalog, dunno if it's on the website I never looked.
If they built the whole motor, I should hope they could tune it. I actually think they make a great product, just way overpriced.
What I can't believe is he's doing it on the stock suspension. I had to mod my suspension like crazy to get it to hook up, and run DOT slicks. And fragged the tranny and u-joints when I added the nitrous

Guido

And I will tell you why.

Our very own TRAXION has a similar combo that ran 12.20's @ 112 on a stock engine. I know from talking to him very often that he had to switch to a #30 injector just to supply his motor with fuel. And I think he commented that the duty cycles were even high on those for his motor. If you are a member of this site you know he is a master tuner of PROM's too and he has tweaked his car to what it is using AFR190's which flow the same as a 195 (out of the box).

I just dont see the stock fuel injectors carrying a car to those kinds of times...

Id like to see some more details on the build then maybe I can become a believer. But at this moment, i say nay. If he had bigger injectors... maybe. And the TPIS tune?? Well maybe he has a good tune on it but anyone Ive ever seen use one of their PROM's just had crap luck. Better off using a stock PROM.

Just my own observations. Like I said, supply some more data... and maybe I will believe. Im very open minded.

rhuarc30

True, I missed the stock injectors part, just no way that the stock injectors will support the power needed to run that fast. Hell I'm running 51's WITH 50lbs of fuel pressure, though that does give me some extra room. And like I said, stock suspension sounds iffy as well.

GofasterFirebird

iTrader: (3)

OK, so maybe he thinks he has 22s. I can get pass that. Maybe the engine builder stuck in 30s or something. But I am more concerned with 122 mph on a full weight car with those heads. Comments on that???

rhuarc30

Sure the 195's will support that kind've horsepower, they'll support well over 500 hp with the right combo NA (though how streetable it would be I dunno). and define full weight, with head's and wheels alone he's lost 100 or more pounds.

Here's an interesting little fact for ya though, If we give the injectors and the suspension question. And stick his engine in DD 2000 then carry it over to Drag 2000 we come up .5 sec's slower and 117 mph. And we all know that these programs tend to be over optimistic in the numbers they come up with.
While I started off willing to give the benefit of the doubt I think I'm gonna join Guido in throwing the

iTrader: (3)

he sent a pic of the car and of it on the strip. It looks like it hooks HARD. I asked him directly he said "No power adders". HMMMMM?

Ed Maher

Some of you guys might not remember, but we used to have a member named ODB who claimed to be running ridiculously quick times in a basic NA 305. After a lot of arguing over it 'not having power adders or stripped' it came out that it had a 2800lb race weight and had a small shot of nitrous on it (but it was hiddden so it didn't count)

Every now and then i guess we get to go through the game of 'Guess what the super fast newbie' is hiding, lol. There isn't much point to lying on the internet though.

The other end of the spectrum are guys like that darcom cat, who posts some ridiculously extreme combo, but then won't tell you what it runs. In that case, the game is 'Guess how bad his tune is' to derate the 9s it should run down to the 12s that it does pull....

1.59 '60 on the stock suspension?

Ok fellas i knew i would take alot of heat on this.Im gonna try to keep this short..Hmm where do i start.I had this motor built last may in hopes of just getting into 11s..not low 11s..It is a 92 L98 block.TPIS s 383 rotating assembly..Callies crank..manley rods..ect ect..good stuff..They put the motor together for me from intake to oilpan..they even put the stock injectors back in it for me..because i was going to break the motor in on them..The motor was not dynos or tuned there..hell it was all i could do to afford the motor assembly.. Anyways when i got the motor in the car the car it seemed to fine with the injectors..no breaking up or leaning out, plugs looked good even after running it hard..First time out to the track it was lazy12.40 @110 hauled *** at the other end but left ****ty..timing was way off..fuel pressure was low around 48 anyways kept playing with it and tuning it and tuned it down to a best of 12.17 @113 173 60 ft..that was it she wouldnt go not faster..mind you i have a dual cat car wit ha flowmaster cat back..Gutted converters..so my next step was to open the exhaust before the axel after the cats..You guys wouldnt believe it..it went right to 11.60s @ 117-118..with best 2 weeks ago of 11.50 @ 118 1.5960ft >so allwinter long ive been wanting to run her opened up,but i knew i would get kicked out where ever i went.lol (No Rollbar)So last friday i had the opportunity.We rented MIR for a day one lane .no tech or anything..Iran 11.62 @117 closed up a few time then i opened her up..it went right ot 11.26 @120.98..Yeah i was surprised..Ran a few more runs..then i iced the intake..thats when it went 11.23 @121.26 not 121.76 that was my mistake.lol.1.56 shortime..If anyone wants to see the timeslips let me know i can email them to you..As far as you ED..Were both in Va..We should meet sometime..Ill let you check my ride from head to toe(so you can see im not lying on the internet)

89ProchargedROC

what kinda intake do you have on that motor?

also, you seem to have a picture of you car online......email it to me and i'll host it for you

bobs89irocz

HOW STREETABLE IS THE ZZX CAM? Im really considering buying the cam and wanted to talk to someone that actually has it. I was going to grow afr 220cc heads with the zzx cam on the combo in my sig, if I put those heads and cam on the car in the sig i sure hope i will be doing every bit of 11.20s. If not i will be very sceatchy about your set up. Anyways any info about the streetablity of your car would be nice, thanks.

Bobby: i think the ZZX is very streetable..Its not for the weak at heart though..You have to have loose converter..3500 or higher she really starts pulling at about 4800..and believe it or not mine pulls to 7000..but i try not to go past 6500..dont wanna stress out the hydaulic roller rockers..youll have more motor than me if you go with those heads..Idont see why you cant go faster than 11.20..Anyways good luck..

Ed Maher

Don't get me wrong. I can believe the ET / MPH for that combo, the only part that doesn't fit is the fuel system, 120mph is obscene, and even blower guys running FMUs won't usually run stock injectors that hard.
If i'm ever down in the richmond area i'll let you know though, i'd love to take a ride in it.

TRAXION

Yea - the fuel system is the only thing that I would be concerned about. I hit 100% duty cycles on my 22lb injectors (@52psi) running only 109mph. I've seen 24lb GM injectors work up to about 120mph with a stock full weight car (and that case was extremely rare). I just don't see 22's supplying enough fuel. I have no doubts that your car ran the times that it did and I have no doubts that it is capable of those times. It's just that maybe they put in bigger injectors. I know that MSD makes bigger injectors that look totally stock. You have to realize that 122mph with stock injectors and stock fuel pump is rather ludicrous. We are talking about 425 rear wheel horsepower (probably more) to produce MPHs like that with such a heavy car. Also, we are talking about producing this horsepower in the UPPER RPMs where duty cycles are strained to the max.

BTW - Nice hooking Great pic! .... and, if for some reason your car is a fluke of nature with its 22lb injectors and stock fuel pump then you should be able to hit the 10's with a set of 36lb SVOs .... unless you already have those in the car j/k

11sec, what do you mean by stock suspension??
Traxion you think that his engine, which is basically the same as yours minus the extra cubes and a cam to match makes 100 more Hp than yours??

Ed Maher

Tim was running a small cam and unported 190s when he ran those times though, so it is entirely feasible for a 383 running a bigger cam (IIRC the ZZX is pretty healthy) and 195s could do 120+

Guido

Ive seen cars with his combo running that time before too but just not using a stock fuel system.

TRAXION

Ed is on the money. When I ran 12.2@112 I had:
218/224 cam
stock unported AFR190s
2800 stall
1-5/8" SLP headers
52mm TB

I now have:
230/245 cam
ported AFR190s
3600 stall
1-3/4" long tubes
58mm TB
AFR HydraRev
'R' series lifters

What I will be lacking is a good catback exhaust. The single 3" just isn't enough. But, this combo should still be easy 11's if it holds together long enough for me to get to the track ... lol

Tim

kevinc

Yeah, and a 305 is basically the same as a 350 minus the extra cubes.

GofasterFirebird

iTrader: (3)

Who has ran almost 122 on a full weight car with stock AFR 195s???? 1 5/8 headers?? Ok, he claims slight exhaust port. Since when did AFR heads need a better I/E ratio? Maybe with a single pattern cam, I guess.


Now trax has put a similar sized cam to that zzx(239 239), better heads than 11secz, better headers, larger stall, hopefully better tuning. Sure he is down 33 cubes, though. But some of that can be made up in lack of air conditioning, power steering, etc. I think trax is down a half point of compression though. But that shouldn't be an issue, maybe a few hp. I still don't believe that 122 mph pass will happen. That is like a 125 nitrous shot on top of his old combo, IMO. Not discrediting trax, b/c I hold my car to his standard, but I am in the process of building a similar combo to 11secz and do not foresee very low 11 second NA passes. Most people like was stated before need AFR 210s solid cam, slicks, suspension work, wideband, etc, to achieve times like these.

GofasterFirebird

iTrader: (3)

Good one KevinC!! The bore size is what matters here. Even with the small bore size i think an AFR headed 305 with 11 to one and a miniram could run a mid 12.

89ProchargedROC

I think his times are feasible....

i had a street racing friend who had a 383 in a lightweight 86IROC that had some out of the box Track 1 heads (similar flow numbers to the out of box AFR 195s), some longtube headers and a healthy solid roller and on some ET Streets his ride was good for 10.80s with a 3.42 gear

so you take away about 40hp for the solid roller and the longtubes and you'll be going 11.20s

Also take into account that he was shifting this thing at 7200 and if he had the proper gear....he probably could've been going 10.60s

GofasterFirebird

iTrader: (3)

what about the lightweight part???

I understand the heat for the injectors..trust me it is as hard for me to believe as you guys..Here is the part number off of them 17086544..the first three #s could be wrong..I had trouble seeing them..TRAX: i do think i have a fluke of nature to be honest.never would i have thought these injectors could with stand this motor.The suspension is stock!!! I do have the front sway bar removed right now.(helped alot).This car has always left really good ..Im gonna try to get some pictures from under the hood for you guys..Other than that i dont know what to tell you fellas..The combo is what i state.. i am not on here to make false claims..i think i just got lucky in this case..But in the future i will be changing a few things and pray for a high 10 on motor.Anyways fellas take care:hail:Bye the way i have done nothing to reduce the weight of this car either..im gonna try to weight it this weekend

Matt87GTA

Hmmm..... I smell a LOT of tuning..... Do you burn your own PROMs or have someone do it for you?

11SEC91Z

iTrader: (4)

TPIS burned the prom for the stock injectors

TRAXION

Knowing how my Level V chip was programmed I am even MORE skeptical. Level V = Junk .... unless they changed something between the time that I bought mine and the time that you bought yours. They left my fuel curve 100% totally stock. But still ... 22lb injectors .... They are good for about 340rwhp or so. You need at least 420 to run 122mph. Plus, I realized that we are talking about an automatic with 1-5/8" headers .... that type of mph for an automatic with small tube headers is crazy power.

bobs89irocz

torque is what makes the car move guys, not hp. You guys up there that are in total disbalife of thiese times obviously havent drove or had a 383 stroker before. It is deffenitly possible with the combo he has. There are a couple of things are are alittle ify but you saw the car, and the slipes. He has a 383 with a mini ram and afrs. Those 3 things right there will put you in the LOW 12's to high 11's. i beleive it can be done and it has been done. Have you guys ever read anything about the zzx cam? its pritty bad ***. Plus afrs and stuff. There are cars and combos out there that leave you in disbeliefe but are actually true. This is one of them. I dont dought that this is possible. I sure hope im running that fast though, i have some crappy heads and cam and i was hopping for 12.2s or lower. I am expecting alot more now.

Ed Maher

I guess you missed the part about the 22lb injectors and junk chip.

I don't doubt the combo could run the times, and neither do most of these people who's opinion are in generally high regard. But with stock injectors and fuel pump on a TPIS chip is like G<x>od touched that car man, lol.

Bort62

Well Obviously not...

I think its the "Stuff" wich is where the magic is.

Please be quiet before you embar*** yourself.

Actually, its too late.
