What is your car running at the track and what mods did you do to your car?

------------------
1987 Black 305 TPI 5spd IROC, seems to be fully loaded, but can't find RPO codes.

AIM: IROC 5spd
http://www.geocities.com/chevy5spdiroc/87Roc.htm

 

Well, I ran a 14.94 @ 91.67 when I had my Edelbrock on my LG4. Now I have a TPI and I hope to have some times in the next month or so.

 

89 GTA 305TPI 5speed, The best i ran was a 15.11 at 93.65 mph (should've been closer to a 14.8 if i knew how to drive). edelbrock headers, highflow-cat, flowmaster on stock cat-back, al driveshaft, also ported plenum, coolant bypass(not that these gain anything). I hope to go again soon (next weekend) with a SLP chip and some sort of coldair.

 

When my car was bone stock except for the jet chip and K&N's, it ran a 14.9 at I think was 94mph but im not sure. It would have been faster if i didn't peel out so much in first (it was my first time to track and I didn't know the track was so slippery). Well I just did all the other mods in my sig and now that my new gears are broken in, I will run this coming wednesday. With a 14.9 before while peeling out in first, I'm hoping all my new mods will get me to 13.9. I'll probably only get 14.2 or something though but who knows.

I had a bunch of other things done to it too. Msd 6a,custom chip,hurst shifter,k@n, the kid who has it now ran a 14.6 but then burned up the clutch and tranny.

my 90 IROC 305 auto ran a 15.2 on motor, (3.73's, dynomax exhaust, and siamesed runners) and a 13.2 on nitrous

 

My times and mods are in my sig, and my car has 110,000 miles on it.

Best 60 FT street tires 1.930
Best MPH street tires 99.29

 

My best times are in the sig.. I had all the mods on the 305 except the headers be4 i spun a bearing on it. I bet i could have ran in the 13's with the headers on the 305.

bjankuski, sounds like a g-tech time to me.

 

14.43 @ 96 with a 2.16 60 ft
no cat, no smog, hooker comp. ceramic coated shorty headers, custom 3 inch y-pipe, stock cat back system with a flowmaster muffler, ported plenum, ported intake base and siamesed into the base 1.5in.
i probably should have ran more like a 14.3x but i did something different to my spark plugs to try to get a better spark but i think it hurt me.
i'm hopin for 14.2 with new plugs and a cutout. it all depends on if i can stick my car or not
Andrew

 

whoa, y not a 3" catback? what size are you headers and arn't SuperComps overkill for a 305, I was thinkin gthe heddman TES headers and y-pipe for 309.99

 

the stock exhaust is a 3 inch cat back
no they aren't overkill they are the 1(5/8) primaries.
and they aren't super comps just competition headers but they are ceramic coated
i love them they were the best mod i did for my car

plus my car is not smog legal, we dont have to worry about that here in Oklahoma we don't even have inspections anymore

I have watched Bjankuski run those numbers with my own two eyes. Very quick car.

 

The numbers in my post are actual drag strip times. The times from my G-tech are faster then then my actual times. The G-tech reads 13.60's at 104 MPH. My G-tech (for reasons unknow to me) will usually read 2-tenth faster then what the car actually runs.

My G-Tech never read very acurate and now that i'm at school in FL the track is only an hr away, i'll just go there and get some real times. I wasn't too happy spending $140 on the G-Tech.

there's a whole bunch of crap in there like exterior mods, but the engine and computer mods, the 14.7 was made on an Ed Wright stage 2, gutted cats (G92), and adjustable fuel pressure regulator. I had the Hi-jacker air shocks pumped up to 50lbs for a better "squat" off the launch. And things like the MSD ignition and coil if that even adds HP I sincerely doubt. I don't know if my web-page still works or not, but if it does, it's at: http://php.iupui.edu/~balyea

A Run of 14.5 Is Possible, But I Have to Wait for My Shifter Springs to Arrive (Mine Are Missing for Some Reason). The Run I Know Which Should Have Achieved This Was Against a Mustang Who Ran a 14.865. I Was Ahead By An Entire Car-Length the Entire Run Until My shifter Hit the Gate For Fourth Gear, Causing Me to Miss the Gear and Grab a Very Disappointing 15.810. What Makes This Story Even Worse to Tell, Is The Fact That I Believe I Had My Best Reaction Time On This Run; a .605 Second Reaction.

now that is abuse of the sig feature. It WAY TOO LONG, my *** , it is loger then this post.

 

Ok here is my combo....what hp do you think I will be pushingand what kind of powerband? I am new to this modding thing(I done an engine swap before tho) and really don't know how to match up cams and such.

1) Port and polish my old LB9 heads with a valve job, new springs(what do you recommend) to replace the TBI head on the car now.

2) Heddman TES headers and Y-pipe to add to my 3" cat-back

3) Port plenum, Edelbrock Hight Flo TPI base and SLP runners.

4) Comp Cams CC08-300-8 Fuel Injection Cam Stats:
Dur(.050) I 206 E 210
Lift I .450 E .480
LSA 112
RPM Range 1000-5000

What do you guys think?

What do you guys think? What kind of time do you think this will get me in the 1/4 miles.....remember i am just learning about modding TPI.

 

Personally, I think the cam is a little weak for street/strip 305. I have and plan on installing a crane cam 2032 214/220 intake/exhaust. 1.6 roller rockers to get lift around .480/.496". home ported/polished TPI heads, I already have edelbrock headers, plan on burning my own chip eventually, and siamesing the base. You all can have you're own opinion but i think the tuned part of TPI engines is a bunch of B/S. I can't think of anything more fun than my engine breaking at 6500+ rpms. Go for a ride in a low 14 sec N/A honda, it will open your eyes. BETTER YET, drive it yourself, ever shift a car at 8000+ rpms taking it easy on the motor(you know how our cars pull from 3000-4500 in 1st, imagine that from 6000-8400 in every gear), my *** , it's fun. I love to hate them and my friend's civic that's faster than most 3rd gens. 14.3 @97 mph, no internal mods to his 1.8L engine. I hate him too.
