Dyno #'s: Vararam + LG headers
I had my car on the dyno this weekend. 348.9 hp & 371.0 tq. I'll post the graph as soon as I get it scanned. This is with Vararam intake and LG logtube headers, no cats. No tuning done on the car. I was happy with the results. Thanks for the great headers, Lou.

Great numbers. Wonder how much was from Vararam seeing you were on a dyno and not in motion. I would guess that most of that increase is from the LG's. Any baseline?
Also, how was your A/F? Why no tuning?
Sorry for all the questions, but I am evaluating the LG's for installation on my car.

I believe most of the difference came from the headers as well. I do plan on getting LS1edit done, but just have not had time to take it to a tuner yet. The A/F looked good (13.0) until the top end then got a little rich (12.8) Autotap showed no KR at all. A tune might squeeze out a little more, but I am happy with the numbers for now. Here is the graph. If it does not show click the link in my sig, I put it there, too.

I can't get the image to work either but good numbers. I think the majority of the numbers are from the LGs, because the Vararam advantages come at speed.

Re: Dyno #'s: Vararam + LG headers (MAGRED2001VETTE)
Thanks for the compliments guys. Maybe webshots is the problem with the pics not posting. I need to find a better place to post pics. Any ideas? No I do not think it hurts to run without a tune. Obviously a tune will yield more HP, but I get no KR, fuel trims look good, A/F looks good. The only problem I have had is getting an O2 code, but that is pretty common with headers.

I am running Autotap to monitor the car. Twice I have got codes for insufficient switching in the Bank 1 Sensor 1. I reset it and it has not come back. I am running sims in the back. Not a big deal. Let me know if you have any more questions.
