Just got back from the Dyno...

I did a lot better than I thought I would, we did 2 runs on a dyno jet, 4th gear pull, 74 degrees out and the best was 332 whp and 338 Wtq, my a/f ratio was all over the place it started out at 13.6 @ 2200 rpm then went down to 12.1 @ 6000 rpm so she needs a tune, but I am still happy with the numbers as all I put into the car was about $350 in mods so far...The video sounds like A$$ in the beginning but once the car is opened up it sounds good.

Basically everything in the sig - $45 ebay intake, $200 exhaust, $30 intake coupler, free ported TB, so actually only about $280 in mods, the catch can and short throw dont help with HP.

Those numbers are pretty good. I did about the same when I had
LT headers only.

That is very healthy for such minimal mods. About the same numbers I got in '04 after my full exhaust and blackwing. I need a tune desperately...

Great idea, and if you are going the intake and cam you might as well add some LT Headers

Make your Vette Exhale all that air you put in

All depends on what the A/F ratio is now. If its still real rich, like they come from GM, then you still have a chunk left. If its close to 12.8:1, theres not much to be gained from a tune. By the #s you put down already, I dont know if you'd see a 15 HP jump from a tune. If it did pick up that much, that would be near incredible for your mods.
That would put you in the 347/348 range, and most of the ones we see near 350 are at least LT header cars.
Damn good numbers for untuned though.
PS. Dont mean to rain on your parade, but just looked at your graph again. The correction factor is set to standard. It should be set to SAE. You'll loose about 7 or 8 HP on SAE, but it is a true-er number. Sorry......

This thread is proof that the Corvette Tax is caused by a mental disorder. You don't need to overspend to make good power.

those numbers arent SAE. They need to be corrected. My guess would be that you are closer to 315rwhp. good luck

See post # 12.....
HP loss is 7-8 between the 2 dif settings. Just went and checked it
PS still very nice numbers at 325 or so. Very respectable for no tune.........

still nice numbers though for just a few mods... but how many times have we seen those numbers from those type of mods?
All LS1's are not created equal.

Not raining on a parade either... this is just rare, but nice to see

I cant convert his graph, but I could post a similar car, both in standard and SAE. It would take 2 graphs. Let me know if you want me to post that. I could do it in the AM first thing. Getting ready to go home in a few.
