Yea, I can elab a little more on the setup for those of you who asked. Got some basic things like alum water pump, adjust fuel pres reg set at 47 psi. 170 deg thermostat, power pullies, stage 2 chip, headers, ypipe, 3 inch cat back, I ported the runners and plenum myself, ....but the launch is where the time comes in. I have nitto drag radials set at 15psi, tubular control arms, panhard rod, and poly bushings. Basically do a 8 sec burn out and launch at 4k. It hooked up for a 1.90 60 ft for the 13.5, but that was the best launch. The t56 has a 2.66 first gear, and my rear end is still the stock australian 3.45. Basically my launch and torque get me the time, and the best trap of 101 is just from having cold air and a healthy running 305. B&m ripper shifter is the best thing i ever did, aside the spec stage 3 clutch. my friend might have that run on tape, but i know the 13.6, and 13.7s were on tape. Either way, the 305 really loses its gas in the highend, and i still hate this motor compared to the ls1. But my best trap of 101 is high when i look at other 305s...but then i see these monkeys driving horrible 2.3 60 ft times and all. im gonna be at lapeer 3 more times this year if any locals wanna meet.

 

Oh yea, i forgot for the one guy....full interior. Its a hard top, not a heavy ttop car, with spohn sfcs, and no power seat, no spare tire. Only options i have are power wind, power lcks, ac. I want to go weigh it at one of those truck stations.....think they will let me? Im guessing about 3350 or so.

What kind of 60 fts do you guys get with bf drags??? can i improve my 1.90 60 ft with a pair of them???

 

awsome,nice times for a 305.

 

What with what this guy listed, for sure its BS......No 305 TPI with those so called Mods is that fast.

 

here is an old site with a TPI car with minor bolt ons running mid 13's

his site was the first performance site i found when i got my 87 IROC back in 97.

he got some very impressive times...stock internals

so it is VERY possible...lots of torque and good traction

 

very good but the problem here is askulte has done great tuning,hedders etc.did you notice he also still uses the t5 tranny,which is waaayy lighter than the t56 and also uses a steeper 1st gear than the t56 its totally possible that the car ran the time claimed but to be that much faster than askultes, not really feelin that one,i am not tryin to be a" richard cranium" but i dont think the clocks were correct for his run,i mean a friend of mine with a marauder(fords attempt to copy an impala)ran back to back 15.70 then all of a sudden he pops off a 14.2(no mods)4 days old!it looked just as slow as the other passes sorry rob!

 

Hey, my RS runs 111-112mph in the 1/4 with just bolt ons! Of course it isn't an LO3

I get a lot of bs flags too but I have come to expect it. You should too with a car that runs like that. If everything is as you say it is, good job on the times. It is nice to see these cars run like they should.

 

actually...other than the hypertech chip...he didn't do any tuning on the car for those runs.

he did tuning after the turbo.

and yea the t5 is lighter, but that isn't gonna make THAT much difference. he also had a 9speaker sound system!!

 

Still, that time is a little hard to swallow. GMHTP has been doing a buildup on a 89 Formula G92 good cammed 305 like yours (code named Blue Thunder), with the factory 5 speed and 3.45 gears. They did nearly identical mods, runners and ported plenum, pullies, headers and full 3" exhaust, among other minor stuff. They needed slicks and ideal conditions at a very good track with a good driver to just barely hit 13s. They weren't running over 100mph though, and all testing done near sea level.

If the times are legit, definately get videos! You'd be a legend amongst the 305 crowd Many people dog the 305, and those that do try to mod and go fast usually fail. Personally, I'd love to see a little 305 TPI running mid 13s on bolt-ons!

Is he making between 250/275 RWHP to make that time with those Mods???
I think NOT.

 

I did get my 86 Trans Am to trap 99mph, but that was with a cam, 52mm TB, headers, full 3" exhaust. Car was an LG4 that I converted to an Speed Density TPI with the 87 TPI heads and stock TPI intake, runners, and plenum.
If the 60' wasn't so bad, I probably would have hit a 13.5-13.7.
My 305 died before I could get it back to the track.

 

13.5 On a full interior???, I think not. 3350???? Try over 4000 with you in it, My old 305 iroc ran a 13.3 on M & H slicks, headers, big gears, no interior and a BIG shot of juice. Your gonna have to try again..

 

Transxtreme, our cars do NOT weigh that much.

My 91 with the 305/auto, full interior, speakers in hatch, full tank of gas and me in it weighed 3660.

 

And you call yourself "Slim"..... 3660# more like "heavy".
