For autocross in ESP, an LT1 4th gen is my fav. Fewer ABS issues, the clutch usually works OK, more gearing options, and way better steering feel.

The EXACT same question was asked here:
http://www.frrax.com/rrforum/index.php?showtopic=10869 Don't feel bad for not searching since this was hard for me to find when I knew it was out there somewhere. |

I have 315's on 17x11's all the way around my 89 TA. Now the do stick out beyond the wheel well but I have adequate turn radius for autox. I by the way like the 3rd gen for reasons already posted especialy overall looks and that masive 4th gen dash. I also agree that the combo to have is an LSX 3rd gen. I would stick with the lighter t5 though. They seem to hold up fine when not drag racing.

I don't think you could make a T5 live behind an LSx (even if you could bolt it up) while driving it as you'd drive an LSx'd third gen. "Poof", nothing but transmission dust...

My solution is likely to involve Motec or similar (or a carb...bwhahahahahahahahaha). I do hate the ECM's in these cars. |

My T5 has survived for a year behind a Firehawk motor, which is as strong or stronger then a stock LS1.

I'm not trying to get into a "road race vs. auto-x" dick swinging contest, but a weekend on the track is probably a year or more of autocross duty. That's not even mentioning the extra heat in running it that hard for that long. If AI could run dog-ring gearboxes, I'd probably have a dog ring T5. Dog rings would get rid of a lot of synchro issues and the straight cut gears get rid of the gear weakness, then you're only dealing with heat and case flex. |

Part of your problem was you had a bad Autoprom. It was the early version that had some issues. After I bought it from you I traded it for a new one from Craig. But I agree, it still takes a lot of effort and patience to tune. I had many 'issues' before I could even get to the point of doing some meaningful tuning. Some of that I brought upon myself by being the only person in the world with a Jerico and a TPI, but there was some other stuff that was out of my control. DIY prom on thirdgen.org is your friend. It is fun when you make a change and it 'works' (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) This post has been edited by StanIROCZ: Jun 24 2009, 12:53 AM |

How do you tell the difference between the new and old Autoproms? I always have issues with mine, something goes haywire and I have to unplug the ECU to reset it. There was also an instance where the engine would stall briefly, but 'restart' just by momentum of the car.

That's not even mentioning the extra heat in running it that hard for that long. My T5 hasn't seen any track time since the 350 got installed last year (persistent oil leak on the engine), but it has seen track time behind the pervious 305. I can see that all the shifting would be a different type of stress on a transmission than what autocross causes, but most of tracking and road racing doesn't launch from a dead stop as autocross does, even if it isn't as hard as a drag race start. I've always believed that it is hard shocks that break transmissions. I wouldn't think that there would be anything preventing putting an oil cooler on the T5. Ether way, my trans has 105+ K miles on it, 25+K under my ownership. I'm sure some day it will blow, I'll just fix it and throw it back in again. |

I must have one of the later ones because the only issue I've had is getting it to simultaneously emulate and datalog. Otherwise I've not had any issues. Tuning takes time, and you have to understand what you're doing. If you are impatient and in a rush, your tune will reflect that. Anything worthwhile takes time, tuning is no different. For those of us that dual purpose our cars, EFI is very much worth it.

Every chassis has its problems that you can go around/fix! Some are easier nowdays than in the past, and some take longer to do... but thats ok to some. It also depends on what chassis you started this little adventure where all on here!
I still think a LS 5.3 powered 3rd gen AI car would be hard to beat! To some it may not! Atleast its all GM! .02 |
