Default The numbers are in! Dynoed FINALLY!

Well I posted a thread about a week ago saying I was going to get a tune this Friday and dyno the car. It's been a long process coming. FINALLY!

I don't have the dyno sheet uploaded...if I did I'd post it.

The car made 351.98 rwhp @ 5800rpms and 355.78 rwtq @ 4600rpm.

I'm going to close up the gap on my plugs and fix an oil leak before I dyno again. Also I'm going to try to install a bung into my header/Y-pipe so that next time he can hook up a wideband directly there instead of just using the sniffer.

Here's a link to the thread where I asked for prediction.

https://ls1tech.com/forums/lt1-lt4-modifications/969662-hp-tq-predictions.html

I can thoroughly say that I am happy as heck! I was hoping for somewhere around 330hp and 320tq. Boy was I pleased! haha!

Videos will be up as soon as they upload.

Nice man I guessed pretty damn close. Take it to the track now and see what it does, again real cool project swapping out the V-6 for the nasty LT1 and T56!

Good attention to detail and making the most of your combo... You would be 380-390 with a decent set of heads,,,,

Congrats

Those are some nice numbers. It's nice to hear about the GTP injectors too.

man thats crazy. I finally got mine dynoed again after the 6speed swap and it put down basically the same numbers ( 352 hp and 357 tq) . I need to get mine back to alvin though, it went pretty lean on the dyno (17.1) i would like to see that graph though they should be close.

Really nice numbers. Good work.

T-Bird you should post up the Dyno Sheet. I would like to see where that cam wants to be shifted.

I would but I don't have a scanner unfortunately. If I can get a hold of one I will.

Went to the track last night and ran the car.

The best 60' I got was a 2.19. I was launching the car from idle basically, I don't want to be another horror story of a 10 bolt exiting stage left...

First run, ran a 9.1 @ 84.3 with a 2.3 60'. I was sooo pissed.

After 3 more runs I finally ended up running a 8.81 @ 85.9 with a 2.1 60'.

Overall the car ran fairly well. I was paranoid the entire time about breaking something so I never really beat the snot out of the car, perhaps next time. I was impressed somewhat with the MPH though.

Very nice numbers! I hear you on the 10-bolt. Got any plans for that, or are you just gonna drive on street tires?

Very cool build-up! Good Job!
