New stock head hotcam dyno numbers
Got it dynod today, check out these new numbers:
1st run
332rwhp/335rwtq
2nd
341rwhp/337rwtq
3rd
355rwhp/350rwtq
The first two run were through the full exhaust, SLP single cats/ypipe, ORP, Borla catback with a vortex cone before muffler. It was still warming up on the first run, it had sat for about 3 hours before I got to run. On the third run I opened up the cutout, I have it welded into the ORP, no cat. This is on stock heads, never been removed. I was pretty happy with the numbers

NO WAY..REALLY?
You got those #'s from JUST A HOTCAM and a performance exhaust ?
I have cnc fully ported lt4 heads and intake and a hotcam (dyno tuned) with alot of other stuff as well and its running tuff but still putting mid 300's on the dyno...What gives

All my other bolton mods are in the sig. I couldnt be any happier with how it's running. I really need to get an e-cutout though. I had a bright idea to get under it and uncap the cutout after two wot runs on the dyno
Burnt the heck out of a few of my fingers. Oh well, it was worth it

Great numbers! Looks like it pulls pretty good up top, what do you shift at?

Not sure, what other mods do you have and what kind of tuning?

Last time I ran it in November I shifted at 6000. I got a Harlan shift light, it makes shifting a lot more accurate than watching the stock tach.

The last time I ran a hotcam it was with LT4 heads, so my stock headed car is a slightly different animal. Thanks for the help.

Skinnies, dr's, and launching around 4500 rpms help. That pick was when I hit 12.9's with boltons before I did the cam. It launches a little harder now
