425 to the ground... If it was a 4v, then i would have guessed 500.

 

[MOTOWN M]

450 - 475 to the wheels

 

[sleepermobile2]

420-440

 

[SVTPete83]

Depends on how high you're gonna spin that thing. 7k and you'll hit 500 no problem.

 

[JeronimoJC]

What's your fuel system good for ? Is this your limiting factor?

What's your CR again?

Do you have other blower pulleys ready to swap?

 

[ctgreddy]

I'm gonna go with 521 assuming you can hit atleast 15psi. I had a buddy with a similar build but had head work and made 540whp.

So i went up to see the car on the dyno at it made 470rwhp at factory redline (6500k). my tuner said that because it was only going to be a street car we didnt want to make it too unpredictable. We only put 16 degrees of timing in it and should allow for it to not get too heat soaked during the summer months. going from 14-16 degrees of timing we picked up 38hp so it would have been over the 500 mark if we upped it.

@jeronimo- the fuel system is a 255lph walbro in pump with a t-rex inline 155lph. We didnt run out of fuel but i will need a 355lph in tank if I want anymore power.

@Ctgreddy- We made 13lbs of boost which is pretty good considering thats through a 4.5" core treadstone (1000hp) intercooler. Im prolly losing 2lbs.

Wut

@zemedici- the vortech kit (which includeds the trex pump) is only good for a little over the 500 mark. if i want to make serious power, in the future, like cams or heads the two little pumps will have to go. hth

I think his question comes from no one makes a 355. At least that I know of. I know of the 255, 320, 340, 400, and 465.

 

[Alysiak00]

im pretty sure they do make a 355 (believe its the gca355). regardless for future mods i would need a slight fuel upgrade, thats all i was trying to say

GCA355 is the part number. I didn't look to hard but it looks like it flows 158lph. You can't take the part number fur granted. I have a 255 in my garage that has 340 or 342 in the part number.

Right On, Thanks For The Info. I Wont Need One For A While. This Upgrade Should Hold Me For A while

 

[sleepermobile2]

You did good !!!! I figured 10-11 with that blower .

 

[SVTPete83]

I made 550 with a 255 and a bap. Good times. Decent numbers. She will be fun to drive!

 

[Alysiak00]

@svt pete- was that on ur cobra or a 2v?

 

[Brutal Metal]

You did good !!!! I figured 10-11 with that blower .

not with a 3.0/10% overdrive combo, that's fairly aggressive.. I'm 3.1 with oem size ATI damper making 13lbs

 

[SVTPete83]

@svt pete- was that on ur cobra or a 2v?

4v but stock heads and cams. I figured with your porting and cams it should level that playing field a bit. I have a 10% od and a 3.12. At 7k I am pushing 15 pounds in 80 degree weather through kooks long tunes with cats.
