what realistic rwhp numbers can I get with this set up ... ??

I have a 07 GT500 totally stock

What can I expect with these options rwhp ( approximately of course):

stock eaton blower
VMP 67 TB
2.5 upper pulley
10% OD ATI lower pulley
170 T stat
afco heat exchanger
JLT CAI
catless H mid pipe
tune

are there any issues with this set up or running 93 octane with a lower and upper pulley on a stick blower ..... wont be used for drag racing just occasional busts of speed

thanks everyone appreciate it

I have almost the same setup (2.6 upper) and put down 582rwhp.

@einehund those #'s are impressive as hell! Is that on US 93?

...might slap on the Monoblade after I do my headers and go for a few dyno pulls just to see where Im at.

I’d say 575 to 590 range. Can certainly run 93, just be easy with the advanced timing in the tune. Certainly a decent amount of boost with the factory Eaton and may run a little warm when you play. Just hoping you have some fans on that AFCO.

Close enough. I think it comes out to 93.8 US equivalent. It was on a pretty chilly day (in the mid 40s*), so i know that helped

oK ...... if i can buy it at the price I want too may switch to a used gen i blower with ported elbow

with a 2.5 pulley VMP TB and catless mid pipes i think i be in the low 600 rwhp range and a
safer way to go than with a 10% OD lower pulley

deal closed

all go fast parts bought and this is what I am doing

- USED VMP GEN I BLOWER WITH PORTED ELBOW WITH 2.6 PULLEY

- NEW VMP 67 TB

- NEW JLT CAI

- NEW LETHAL OFF ROAD CATLESS X PIPE
- afco heat exchanger
- 08 lower pulley

any guess with this set up where I will be rwhp ??

I made 650/650 with a similar setup.

more than I thought ...... as I said my VMP II blower with the same supporting cast dynoed at 664rwhp on a conservative tune

thank you !!

@1badsho Don't forget, 1320Junkie can port just about anything if the urge ever hits to maximize the flow potential. Find him on facebook. used to be a regular on here too.

I have a call into Billett Pro shop for the same and to see what they will charge to polish the GEN I to a bright shiney blower

Go with BPS. They will take care of you with no problem.

It will be $600 or so unless prices have gone up.

Spoke to them this am. $450 to port and $1200 to polish and they only do it in the winter when things are slow because of the man hours.

About a 30 hp gain

that's a good price for the port job.
