Just cannow wait to see what my car will do, i am hoping for sub 7.5s in the 1/8th, would make me happy as hell, dont see why it couldnt do better, my last 383 with stock ported GM heads and a 288HR cam did 7.4x at best, so this with deeper gears and what i consider a better engine should go as fast i think, we will see. I know a set of pro ported 243 castings would unlock a lot of power in this 6.0.

Specs of car if you dont know it:

Victor Jr intake with MSD ignition controller

750 Pro form carb(mechanical sec)

LQ4, milled and home ported 317(.030)

Trex cam with matching springs/locks/retainers/pushrods

Hawks 1 3/4 primary swap headers, 3 inch collectors with dual 3 inch and 1 chamber flows with turn downs

Car is a T56 trans with CF DFX clutch and hays FW

Moser 12 bolt with 4.30 gears

Tires will be MT ET streets 26x11.5x16

CE sub frames, BMR panhard, Spohn TQ arm

So, i will be osting results should the car not decide to break. It has no issues pulling to 7000 RPM and makes power pulling till the rev limiter says hi. So far i have dusted a GTR nissan, a 91 5.0 LX with heads, cam and 150 shot could not pull on me and an array of other rides that just didnt stack up on the street, my budies 71 Nova ran 7.5x at best ad i murder him as well, but the street and track are two different worlds. Wish me luck and no broken parts, LOL.

i should hope it runs 7.4 in the 1/8th, there are several cam only ls1 cars running 7.1X to 7.2 in the 1/8th without so much cam or gear

my full weight LS1 car with t56 and 4.30's with those same tires went 7.44. was making 376rwhp at the time. i would think yours should do at least that being lighter, more cubes, bigger cam....

Hope i can run low 8's in my TA tomorrow if i go. I'm gonna try to make it if i can get out of work early

ZONES89RS

Hope you make it out, more the merrier.


Well, you guys have me confident i should make some desired times, i have a buddy with a helmet so i hope i wont get kicked off....LOL.

Then ext visit will be on a 150 shot of gas, just got the window switch, waiting on fuel cell and fuel pump.

How are your clutch/shifting skills?

Remind me, what are the details on your clutch? Flywheel, clutch brand/type, MC, etc.

ZONES89RS

iTrader: (2)

I can shift with the best, there is someone that is better but i am a damn good gear banger, always have had a stick and always trying to get better.

It is a Hays flywheel, centerforce DFX clutch and pressure plate. This clutch does well on the street, i hope it slips a touch so the tires dont break, but i doubt they will.

ZONES89RS

iTrader: (2)

Pathetic, car does not want to 60 foot to save my life, 8.1 was the best with a 1.9 60 foot, launching at 5100 on the two step, best trap speed was 91.65 MPH. So, the MPH says it should go 7.4 or a touch quicker if the 60 was down, i am disappointed, but being a 6 speed, i guess i will just have to live witht he fact it is a street car not a race car. I did want a quicker trap speed, but the 317s are holding back compression and the Trex doesnt have the mid range to carry the car into a good 60 foot after i launch, so, i wish i went smaller but oh well.

xpndbl3

iTrader: (5)

mph is down a bunch, get that thing on a dyno and figure out where the lost HP is. Whether it's timing, or jetting something is off. Put it on a 28x10.5 stiff sidewall slick and you should have no trouble 60' that car.

Going fast isn't as easy as other peoples time slips

ZONES89RS

iTrader: (2)

Yea, i figure the 26" tire would make the 4.30s happy in the 1/8th. I cannot wait to dyno the damn thing and lean it out and get the timing dialed in to optimal power. I just wish i had some ported 243s to swap out while i was at it. Car has all the top end in the world and i shoudl have just went with a smaller cam like i wanted but the Trex was cheap from a guy on tech.

Orr89RocZ

iTrader: (20)

car sounded good! You have a big cam with a high powerband. Short first gear too so the 60 is gonna be very picky on how you do the 1-2 shift. It looked like you were in and out of first gear by the 60 foot mark.

ZONES89RS

iTrader: (2)

Yea, i had it down on the last pass and still only got the 1.9 60 foot, so i was like whatever.

DIGGLER

iTrader: (1)

why are you trying to launch it at such a low rpm? those tires worked great for my car, you just need to know how to go about making the car work. i had a 1.53 60' and went 93mph on my 7.44 pass.

Orr89RocZ

iTrader: (20)

NOt sure how high you left at, but it definately wanted to hook and then bog, so it needs abit more power or rpm or both to keep it rolling

DIGGLER

iTrader: (1)

not sure of the suspension setup, but the rpms need to be 6200-6500ish on the leave. imo, of course.

Orr89RocZ

iTrader: (20)

front looks very soft too, that front end comes up quick. I dont think he went over 5000 on the launch. 6000 seems high but may work good with that gearing and short tire

DIGGLER

iTrader: (1)

if the car is dead hooking, he will have to keep raising his launch rpm until its not bogging any more. depending on how the car hits the tires and how much weight transfer, he may need more than 6500rpms.... also, if the car is hooking that well, expect things to start breaking. especially if there is a posi in the 12 bolt.
the 1st gear ratio is 2.66 i believe, and that makes the car want to either spin or bog if it hooks. a 2.9x ratio out of a '93 t56 would make it work better...

ZONES89RS

iTrader: (2)

Hell, i didnt think 5100 was low! LOL

Spohn TQ arm and T56 swap crossmember with the TQ arm hooked to it.

Well, that is why i did not try going above 5100, did want to break anything. But i am sure launching at 6000 was the key because the 5100 NEARLY bogged but went, the 60s were 2.0 and the 5100 was 1.9, so it was getting where it wanted to be. Just hitting the two step to 5100 was kinda weird(nerve racking).

how's it pull with the 750 and vic jr? i'm thinking of making a change....

DIGGLER

iTrader: (1)

a fast 90 or 92 would work just as good unless you need to turn it over 7k, and then the single plane will just keep going.

ZONES89RS

iTrader: (2)

I love it, my only issue is my Pro Form carb is not a perfect cruiser since it is made for idle or WOT. But, it is not that bad, Pro systems will get ahold of it and make it perfect when i get the cash. But the Fast 90/92 lop off air before 300 CFM on these engines, VS the Vic Jr does not, so the power is there. So far the 6.0 we built with the Torqer V2 is a BEAST with the same setup i have, traps 96 MPH in the 1/8th, my car however once rolling, that is when i do damage to other cars on the street, this things top end is kind of crazy. With ported 243s i will pick up allot more power and some more mid range TQ witht he compression increase.

Did some tuning at the track and my buddies 383 in his 02 SS that was putting about a car and a half to 2 cars on my from a roll is now staying wherever he starts and cannot put land on me, holds at a half a fender. So i have improved the tune since we last ran by a good bit i guess.

Shagwell

A clutch car should launch within 1k of peak rpm/shift point. If it won't you need to work on the set-up/tune-up till it will if you want to optimize it.

xpndbl3

iTrader: (5)

this thing running better yet?

mw66nova

iTrader: (13)

yeah, i'm curious too.

xpndbl3

iTrader: (5)

updates?

ZONES89RS

iTrader: (2)

Sorry fellas, i have just been driving it on the street daily, drug many cars on the street, just dont want to break my clutch trying to get a good 1/8th mile time. Drug a 91 stang with gears, cam and a 175 shot of dope, going to put the 150 shot on it next month, then i might go back to see what it does on dope, bet it doesnt bog then. LOL.

ZONES89RS

iTrader: (2)

Oh yea, since i am wanting a car to beat on at the track without worry of the 60 foot from a cam too big or any of that i am going to be doing a single turbo 5.3 or 6.0 in my 90 RS with a stalled TH350.

This was playing around today taking a buddy for a ride, i must say, these are my longest back marks to date:

xpndbl3

iTrader: (5)

i WISH mine would peel out on the street just stabbing it....but alas it just barely spins and goes

DIGGLER

iTrader: (1)

my LS1 car spins that far but doesnt make much if any stripes in the road. it is actually one of the worst hooking cars i can think of on the street. it just sucks.

ZONES89RS

iTrader: (2)

I pulled a 1st gear stab, smashed the brakes, clutched to second gear and stood on it. Stabbing it in first doesnt leave as hard of a black mark, but it is still there and you can see the 1 2 shift further down.

Orr89RocZ

iTrader: (20)

reminds me of the turbo car. Even with ET streets, 2.73 gears in 3rd gear with the Th400, it will roast tires just about as far as you want to go... Its useless unless your above 50-55 mph and use 3rd gear for the pull.

Your car looks fun man Love that top end I bet

ZONES89RS

iTrader: (2)

Yea, the cam makes allot up top, i wish i went with a smaller cam when it comes to the track, but it isnt a track car so

gtpro700

Wait so smaller cams are for the track and larger cams for street something is wrong with this picture. If your car launched in powerband and you shifted it and it stays in its powerband it would do great at the track. How do cars with large cams do great at the track then? Not being an *** but that is not the problem when it comes to your track times.

ZONES89RS

iTrader: (2)

In my application, a T56 bogs launching on slicks at 5000 RPM at the track, launching at 6000 or 6500 might be fine, but i do not want to break my street car. My car with a 4500 stall or so would be great, but for me to have a car that is fun at the track and not have to launch at the moon would need a cam that makes power down low and mid range, mine has no low end what so ever.

Big cam, big stall, ig gear, works great, a clutch that clamps and drops RPM out of the power band is the missing key for me. But, it is not a track car so i am just going to leave it alone. There are stock bottom end LS1 that have gone 10.4x with a stalled auto, not with a manual.

DIGGLER

iTrader: (1)

mine made 376 rwhp and knocked down 1.53 60's with the 6 speed.7.40's in the 1/8.

ZONES89RS

iTrader: (2)

Must be nice. My buddies nova does consistent 7.5s and at the track he would whoop me, but on the street...he wants a LS or a big block now. LOL.

Shagwell

He noted several variables that don't add up well. The "big" cam was not neccessarily the culprit of his "problems" just that it doesn't suit the rest of his combo. A nice bump in compression to help that cam and/or a smaller cam would help the combo out as a whole thus making it run better numbers.

I'm very leary of 12-bolt tq arm rears and a manual trans. I've seen several 12-bolts killed with an aggressive clutch launch.

ZONES89RS

iTrader: (2)

Well, no issues yet, mine was a used unit and the myth of the TQ arm bolts backing out so far has not happened to me and the rear is quiet(except for the ratcheting sound when making low speed turns).

z28freak84

Im curious to whether or not you have a fuel issue causing the bog on the launch???

ZONES89RS

iTrader: (2)

No, i am fine on the street launching where it can wrap out and sin freely, so i think i would notice a big there too right?

z28freak84

Noo. theres no load when its spinning.. If you dont have jet extensions, that would do it, or if the fuel is sloshing away from the pick-up...

ZONES89RS

iTrader: (2)

Actually, i wouldnt mind trying that at the track, but for me it was simply the clutch clamping hard and dropping below aggressive operating range, this cam does not come to life till 4500 and it dropped to 3000 or so, but it wouldnt hurt to test that out. I need to look in my HP and see if it has the extensions in it.
