Quickiest L98 naturally aspirated (long runner)?
What is the best E.T. and Trap Speed anyone has been able to get out of a long runner TPI on the motor? Please mention mods made.
Updated Question:
Thanks for the response guys. I guess I should have asked -->What is the quickest 350 TPI (longer runner setup)that you have ever heard of -naturally aspirated? Not just your car. I'm talking friends cars, read about it somewhere, saw it at the track etc. If you remember -mention the mods on it. I want an 11sec long runner TPI combo(on the motor)<--is it possible?

My 87 L98 best time is 12.96@107mph......The mods I did were..350 bored .030 over, silv-o-lite hypereutectic pistons(crap)Crane compu-cam 2050 (non-roller) shoulda kept the roller...trickflow heads and ported the base and plenum and gasket matched everything, stock injectors and TB and a hypercrap chip..cut-out airboxes and accell external coil..B&M torque convertor(2500-2800 I think) and a th-350 tranny with a full competition, full manual shift kit(the 700r4 crapped out a month after I put the motor in)Shorty headers and deleted the catalytic convertor option..hehehe stock 9-bolt rear end...took me alot of fiddling with it because for a month after I built this setup it wouldnt go any lower then 13.2@104mph...but finally found the right timing and Fuel pressure settings and ran consistant 12.6's.

Corvette Fever 10/96 did an article on a '87 vette and the most they got from it with the long runners was 12.5@105 on motor and 11.3@115 with nitrous. After a miniram was installed the times dropped to 12.3@109 motor and 10.9@123 with nitrous.

Actually joel I found the compucam 2050 to be on the small side, maybe I'm wrong but it is as big as I could go with the trickflows at the time without upgrading them...this was 2 years ago, the motor is since been torn down and is resting on the machine shop floor to make way for a 350 .040 over, decked with all forged and balanced rotating assembly, pro-action 23º aluminum heads with a brodix hi-rise manifold and unsure on the card but leaning towards a dominator 850cfm...but getting back to my last combo it took alot of fiddling to get down to the 12's, The compucam actually had a smooth idle with the tpi...compared to my brothers camaro that had the same cam with a carb, his car had the rumbly idle...I had the b&m holeshot 3000 convertor with th-350 and stock 3.27 rear gears...

Thanks, I just wanted to make sure this cam wasn't 'over aggressive' as i'm after a mild performance for a daily driver (&TPI)
I should be ably to get away with a converter and some porting on the stock parts with trick flows... They recommend 3.73s or higher and i'm thinking they're full of it... not in a f body, maybe a b-body...
Thanks again...

What did most L98 cars run stock? Like 14.4-14.7 right?
------------------
1980 Camaro, '88 Police 350 engine, Headers, full exhaust, completely redone, my baby!
1988 Iroc-Z L98, MSD 6a, Accel coil, K+N's, Airfoil, Coolant Bypass, Flowmaster, Gears, Late model Bose, I like the 80 better

I ran 12.58@108mph NA on the stock 350 bottom end in full street trim (NO skinnies, Stock body panels, swaybars intact, full interior, etc). This car would have easily gone 12.4's@110 with tuning and track trim. But, I swapped to the MiniRam for more topend power (I'm not a torque freak).
Check out Mike Davis. His setup has also gone 12.5's@108mph. However, Mike is not swapping to a different intake so he'll be in the low 12's fairly soon ... NA on a 350.
Mid 12's on the stock 350 bottom end with a fully upgraded TPI, heads, cam, and converter is fairly easy to do. Its when you want to get into the low 12's NA with a 350 that the TPI begins to show its weakness.

I ran a 12.42 @ 109 mph with a 1.70 60 ft with my 190,000 mile 350 L98 a few years ago with a raceweight of 3500 lbs. A lightweight racing buddy hit a 110 mph in (3400 raceweight), but he didn't hook so et didn't improve, I think he could've easily hit a 12.3 with a solid hook.
I switched to the Superram and a Vig converter and managed to knock the et down to 12.12 @ 111 mph with a 1.65 60 foot, however this was with the wrong cam for the SR, the right cam and a shot at the 11's could have been reality. The same lightweight friend ran a 112 mph, but didn't hook again with this set-up.
For a few more details, visit the section "My Set-up and Results" in my webpage.
I've never heard of a naturally aspirated 350 hit the 11's with long tube runners, but I would imagine a 383 could wiggle in.
In my opinion, the Long Tube runners are a joke... go with either the SR or MR if you want to make respectable power... things get easier when your rpm band expands a bit.
hope this kinda helps.

I didn't do any tweaking/fiddling at all I just wanted to see what the switch to dual exhaust was gonna do - And I hit the 5000 rpm brick wall that I use to hear about but didn't belive because when I had the T-5, 3.73, TES, Dynomax cat back I was in the high thirteens reving past 6000 so I figured the long runner set up was cool- but 13s is still too slow so I switched to duals -
When I made those runs the engine pulled ok to 5100 - I wanted to short shift first any way so I threw it in second and it went to 5100 - I glance at the road then back down and it was at like 5200 -what the hell is that its not climbing - so I throw it in third and cross the line at like 4800- both times-
bottom line though is that I got too much exhaust and not enough intake and more money than brains

You're not a sucky driver. You just need to drop the happer at 4-5K with slicks and a 12-bolt. There's your 12 A perfect example are my times before the vigilante and after the vigilante. Before the vig (i.e. before dropping the hammer) I could only get 13.0s. After the vigilante 12.5's were easy because my 60ft went from 2.0 to 1.7

Tim Burgess probably has the best e/t's. He has run high 12's (can't recall exactly) naturally aspirated. I know because it was against me. His car is driven daily, and emissions legal. Oh, it's a 305 TPI. Sorry about that 350 guys.

Hi Whiterocz,
This is a nice forum !!!
Yeah in my webpage, I actually have 2 video's of me racing a couple of Viper racing buddies. Go to the "Video" section to see them. Those Vipers are definitely the real deal with good drivers... which these guys are. Sometime in the near future I may add one to the garage... we'll see.

I think I talked to you when I went to Carlsbad. I was the guy who walked up and complimented you on how well you car ran. I told you about the WELLS SU-145 MAF sensor. I have to compliment you again, you have a great sleeper on your hands. By the way what kind of exhaust/mufflers do you run, your car sounds awesome (mellow, deep, smooth, and powerful sound). Your car looks very familiar in the pictures.
Are you that guy, or do I have you confused with someone else?

Willie: I noticed in your sig. that you're planning on running 15 psi. Are you making any additional engine modifications to comfortably withstand that level of boost? Is all your stuff forged?
While I'm at it, here are some unrelated questions that I've been accumulating for a while now.
1. At what level of boost does your water injection activate?
2. Are you going to update your website, and are you going to include pics of the ATI installation? Did you switch to a serpentine belt?
3. Finally, how did you fit your Jacobs coil over there? Is there more room under the hood of an IROC than a T/A? I had to screw mine to the firewall, which necessitated removing about four relays and rerouting them under the master cylinder so I could mount them on the inside of the wheel well. Keeping the wiring simultaneously off the headers and off the steering column was a PITA. If I had room to put it over there, I'd like to know.
Good luck hitting, 11's. Keep us posted.

I don't think he like to give away his secret to his sucess. I don't blame him. What I would like to know though is where he got the water inj or did he make it and with what.

GreenShamrock,
Yeah, I think thats me, I remember somebody telling me about the Wells MAF when I was changing my tires one day.
Thanks for the compliment.
Have you tried that MAF yet ?? Any improvement ??
cheers,
Todd

so far my best run to date with my 355 TPI is a 16.1.
Now that the car is running well and the tranny doesn't slip as badly, I'm expecting at least high 15s.
If I can get the silly-assed trans to stop shifting at 6k, and get posi, I'm guessing I'd be somewhere in the very low 14 second range.

The water injection setup originally came with my Paxton. Then I replaced the cheap plastic Anco pump with a 100-psig Carroll Supercharging pump. More on this in a succeeding reply.

I had to make some modifications to fit the water injection to the ATI setup. I just finished this last weekend and it works great!

Yes, I converted to serpentine. Then I completely rewired all my circuitry. Then I installed the D1SC.

This pic is already outdated. It was taken after the ATI installation, but before my cowl induction hood, Superfueler and custom airbox (which eliminates the K&N cone just above the header!).

I'll let you know when I convert to TPI (soon). Of course I won't have any means of comparing, I am going to just go straight to the Wells MAF.

John M. the 11.39 is a long runner, look at the link below on that site it says "87 corvette" and it discribes the mods - it has ASM long tube runners. How is that thing so fast for a mild TPI???

The main page says the Vette is a 383 stroker. The link says it's a 350. ????

Hey John, he's saying it was a "ZZ" 350, then bored .030 over with a 3.75 crank. It's listed right under it.
This was a link he listed with an even slightly quicker 383 long tube set up. Looks like a near identical combo,, and it looks like they run at the same track.
