6SpeedWS6Formula

I've looked around this site and the internet and can't find any actual dyno shhets for a Stock(or very nearly so) Ram Air 98-00 LS1. I can find plenty of numbers but I want to see the curve over the RPM range. If anyone has one can they post it or point me to where I can find one?

any stock ls1 dyno graph will be sufficient provided there of the same tranny as what your looking for.

Hey how about a 02 WS6 w/ a lid and a cat-back?


Here's mine from this morning with a Direc-Flo airlid and a TSP Rumbler.

those are good numbers for the mods

02 WS6 is that without a tune? Thanks for the graph, don't know how much a difference the LS6 intake, cat-back and lid make but i assume the torque curve is relatively unchanged in shape, just moved up hopefully.

Found exactly what I need. I feel dumb, but for anyone that looks at this thread wanting to find this info this is where I found it:

But if you do have a stock M6 98-00 LS1 dyno that goes all the way out to 6k please still post it this one gets weird after 5.6k.

"This particular car is a 1998 Z28 with a .3.42 six speed manual transmission. The only mods performed to the car at the time of these tests were an SLP Cat Back system , SLP Y pipe, and a K&N air filter"

Thanks for the dyno, we should just turn this into the dyno thread. Not to be off topic but how did you run upto nearly 6.3k RPM?

thats not my dyno. and stock fuel cutoff is 6250.

Really? I've had the car a month and a half and put only about 600 miles on it and only pushed it up there a half dozen times. I thought the redline was listed and painted at 6000RPM. So my stock WS6 can rev to 6250 before the engine cuts it off?

6200 cutoff
6199 resume

according to my stock 98 bin (HPT) file.

My graph is without a tune, FYI.

My tach must be off cause I was watching the revs and my car hit fuel cutoff at what the guage indicated as being 5800-5900 rpms.

stock tachs are sometimes off. get a shift light
