AI 200CC Dyno Numbers
AI 200CC Dyno Numbers I finally made it to the dyno. Car put down 446rwhp @ 6100 and 423rwtq at 4200. The car has more in it. I seem to be having computer problems. The program was showing a quad driver 1 and 3 failure and nothing we did to the program made a difference to the air fuel ratio. The only thing I could do was jack up the fuel pressure. The car runs around 13:1 all the way till about 4700 and then it starts running lean. We ran it to 6100 then the air fuel hit 14:5 so, we shut it down. That's where we made 446. By this point it was heat soaked. I think it has about 460 in it. We'll find out when I get this computer stuff sorted out. I'll post a dyno sheet when I get the chance. I got called into work tonight.

Is it a head swap on a otherwise unchanged motor, or a drastically changed motor? I ask because I'm curious if there is something to compare that to 
Great numbers though!
Great numbers though! ..... and why is the ls1 so godly again???
I mean 450-460rwhp is fairly common on h/c ls1's... some getting 500rwhp.
So a good set of ported stockers and nice bumpstick to even the playing field. =)

It's a budget 383 that my dad and I put together in the shop. 12:1, cam is hydraulic roller. Lift 600< duration is 230<. Tuner thinks it has about 460 at the rear wheels with everything sorted out.

Unlike most LT1 owners, they choose to spend the money on qaulity head n cam setups and do things the right way.
They also dont blow money shitty aftermarket heads and leave them unported.
LT1 guys like to build strokers with poor flowing heads, it seems to be a trend for the past 7 years.

I've only been in a couple vehicles that had a real set of *****, and can only imagine how fun something with over 375hp (not to mention 445-460!) would be
Parents asked me once why I bought a Firebird (my 92, motor blew and sold it), and then later on purchased another... Only real, but truthful, answer I could give was that I'm addicted to G-Forced Specifically longitudinal, but lateral G's are fun too! Not very many places to safely experience the latter though. But I digress, and am rambling >_> LS1 Tech Stories

Not that I want to further the argument/debate, but some of us run LTx due to it being what we like, some because it's the vehicle it comes with they can afford, others it's because of the breed. While it is a GEN II, it's really a GEN I at heart, and that's where it all started! You just can't get the sound from an LSx that you can from a LTx! And if the GEN II wasn't at an EOL (end of life) when it came out in 92 there'd be more aftermarket for us. I think that the aftermarket companies may have gotten word from a little bird that GM was already (or about to) working on a pretty much brand new motor. Could easily have been why Edel decided against releasing the LTx intake way back when it was first announced. As it's been said many times, I don't think any of us (well ok I remember one person) would deny getting a GEN III motor swapped into our car It is a great motor, but still, the LTx isn't anything to scoff at if it's in the right hands! Just needs a bit more owner dedication, love, and a few more bucks to get it to a GEN III's power level

Couldn't have said it better myself. In general LT1's have gotten slower over the years instead progressing like they should be doing.

Those are some pretty good numbers. I'd like to see what it can do once it is fully sorted out.
Haha, that's an absolutely 100% correct statement and I find it absolutely hilarious.

glad to see there's a company out there that continues to show repeatable results from one car to the next.
there are probably 10 business's you can call, and buy a 450+rwhp setup for an LS1, there are probably 2 for the LT1.
either way, it's nice that a man can pick up a phone, dial 11 digits, and tell someone on the other end the EXACT results they want out of their car, and actually get them.
wish I had the jack for an AI setup. I'm too much of a tight-*** to spend the money right now.

Unported DART heads with mild cam. Times in sig. With weight reduction, suspension and a nice heads/cam combo there's no reason an LT1 car can't go 10's. It's just people decide to blow it on building badass motors but have nothing else to back it up.
Nice numbers as usual from AI stuff I completely agree with what slick1831 said.....most LT1 owners put crappy heads on their engines and it's no wonder why they never perform. It really gives the LT1 a poor representation of what it can do!

Its sad to see stock bottom end 5.0s with heads n cams getting better numbers than some peoples Lt1 strokers
They have really shitty heads, yet they spend the money on qaulity shops and get it done the right way....
