Thunder550 is now the proud owner of my turbo system.

Yeah, DCR will be 9.0:1. It will be on the edge but people have done as much as 9.2. If worst comes to worst i'll just put a little larger cam in it to bleed some off. Also, I still have my meth inj and might use it. I'll try out the 60lbers and see how they do. They were running fine with the turbo don't see a reason to swap them really? If the wife thought you had about 2" more than needed but it was getting the job done just fine, would you be interested in downsizing? I dunno, I may just go with the L76 intake since it already has the 90mm tb and 44lbers and get the money out of mine.

I'm guessing a very reliable 420-440. With the 6 speed that is going to be a blast and have a killer sound to top it off.

e just put down thsoe numbers with a 402, milled L92s,L76 244/250 59x/59x 112, 11.1cr.....so im sure youll be closer to high 400s....his seutp is like mine so i should be close to his.

be totally sweet to see 530-540rwhp with a 6speed

@ the -2"

I had forgot about the 6 speed, so I'ma guessin' 450-475 now, since you're talking about a Dynojet
I think you will enjoy this set-up more than any you've had so far, and "should" have a fun daily driver which will require very little upkeep once you get the tune right. 450+rwhp w/ a six speed manual in a RCSB should be bad ***, and good for low 12's or better I would expect. Do you plan on taking it to the track?

I figured the opinions would be widespread. Somewhat uncharted territory. I'm certainly interested in what will happen as are many others. That is what makes it fun is no one knows?

Yeah, it will be at the track. Banging gears and raising hell!

Here is the best comparison dyno I can find to what I have on a LS2 Trailblazer SS.

Current dyno: Bowl blended L92 w\stock valves and new cam

mods:
-Stainless works headers
-Single Magnaflow exhaust
-Cold air intake
-Yank 3600 converter
-ASP pulley
-L92 heads and intake setup
-custom cam 224\?-? nitrous cam !
-stock gears and rims\tires

UNLOCKED numbers,but not to bad for a 224\xxx cam to start with

NOTE The dyno graph starts out low due to having to roll into the throttle and full throttle about 4600 RPM

Cams appear to be very similar.
Biggest differences I can see:
-This one is automatic with converter unlocked, mine a 6 speed.
-I have about a point more compression.
-I have a carb style intake.

I don't think 450rwhp on a dynojet should be a problem do you?
