700rwhp with stock tvs pulley and 10%lower?

[justablur91]

finishing up my 13 TVS swap on my 07 GT500 im debating on leaving the stock 2.7 tvs pulley or going down to 2.5 my goal is to hit 700. what kind of boost will i make with stock pulley and current mods below?
13/14 TVS
CJ65
JLT123
10% lower
#56 injectors
BAP
long tubes

You'll want as much boost as you can to hit 700 on a non-inflated dyno. However, I would leave the stock pulley on there and see what she's got with it. I would be worried about running all of that boost on pump gas, I believe that would be over 20lbs if you added the smaller pulley

i was thinking around 18-19lbs with 2.5/10%, i read another post where a guy made 694 with stock tvs pulley and lower cj tb, jlt 123, 72lb injectors and long tubes at 15lbs of boost

I say port the blower, throttle body and gain some extra ponies that way rather that adding more boost.

not looking to spend $800-$1000 on port work at the moment i just got the car together

Didn't notice you said 2.5, I was thinking 2.4 pulley. Upper pulley swaps are so easy. I'd just see what it does with the stock upper and if the logs look good and you want more, swap the smaller one on

 

[justablur91]

yeah i think i may just leave the upper alone for now and see what it does then drop to a 2.5 if im not where i want to be. gotta be able to get around 690-700 with what ive got

With a 2.4 & 10% OD and your mods on 93 octane you would be very close if you don't have stock cats and are close to sea level with a good tune.

 

[justablur91]

im running long tubes to 3" x with high flow cats on 93. smallest pulley i will run is a 2.5 with my injectors

And to think I'm going for 690 to 700 rwhp with my little 2.1 Eaton this week lol getting ready for nmra all supporting mods on e85 and c85 looking for the eaton record

 

[crazy4life]

660 on two different dynojets. Mods in my sig. Have to look up my dyno sheet but think my boost was 17.3

 

[justablur91]

that was with the stock upper pulley?

 

[crazy4life]

Yup

 

[justablur91]

you plan on going with a smaller pulley? 660 is a nice number

 

[crazy4life]

Probably not gonna increase the boost over what I have now or i would have to run some Torco with the 93 just in case.

With stock pulley 13 TVS & 10% lower pulled 688 rwhp with 91 octane on my 07. Have other supporting mods; 72 injectors, BAP, off road H pipe, etc., etc.. 13 TVS with 10% lower gives you crazy HP from the bottom up!!!

 

[justablur91]

688 thats awesome id be happy with that how much boost were you at?

 

[builttodrive]

I'm told I should see 700-750 RWHP on my new set up:

2.3 FRPP TVS
2.6 Upper
10% Lower
!23mm JLT
67MM VMP TB
Dnatech long tube with offroad X
ID1,000 Injectors and dual VMP BAP's on E85
