I retuned a local guy with 110 octane couple weeks ago with a FPgreen.

Before, he did 374whp/328wtq on 100 oct, 25psi peak.

Retuned on 110 octane:

2005 Evo 8

Mods:

TBE no cat
GSC S1 cams
Stock cam gears
Tubular header
FPgreen turbo
Tubular 02 housing
Sun HyperForce
GST Open Filter
Denso 720cc injectors
Fuel Pump
FMIC
Boost Assembly (ecu-controlled boost)
110 octane
Factory ECU and MAF

403whp / 360wtq

27psi peak to 23psi at 7400rpm.

Low reading mustang dyno. 400 is basically the "holy grail" on this dyno on a turbo like this. First FPgreen locally that has done over 400.

91 octane fpgreen equipped 8's and 9's do approx 325-345whp on this dyno, depending on mod level.

Keep in mind this is "sane" boost, not the 30+ psi I see others doing, not that 30+ is a bad thing, but this guy tracks and autox's this car so I felt 28+ would be pushing it.

There is more left in it if it was a more aggressive tune. The tubular header added a bunch of lag to the car but I'm sure it isn't a big deal with the power being what it is.

Oh, the car only weighs 26XXlbs without driver. Rocket for sure.

 

Peak tq that late? Interesting.

Good numbers must be a blasttt.

Yea the megan style tubular headers added a bunch of lag (about 300-400rpm) which I found a little odd.

He might be going back to the stock (ported) exhaust manifold here soon.

 

Great #'s.

A ported stock exhaust and intake mani > megan headers

 

26xx pounds wow that's light. Would you happen to have any pictures of the car?

 

26XXlbs!! thats light..... What has been done for the weight reductions? Is it an RS? Very curious. This has to be fully stripped and gutted.

 

Because your car is heavier?

What was the A/F on the 110 if you don't mind me asking?

 

ya, my car is light as well. Curious to see if this car is caged too and what all has been done to it to lighten it. Because my car weighed 2880lbs without driver. however I do have roll bar, AC, speakers, etc...

 

thats good on that dyno. kinda makes me want one over a bigger turbo

 

wow thats good numbers to be on a mustang dyno. im pretty impressed by it. im in the process of doing my build with a green w/ forge actuator, jun 272/272 combo with springs and type 1 retainers, ble lifters and new stem seals and seat locators. the rest of my mods are in my sig. cant wait to see what i put down when i get done.

 

What brand of fuel was this? Great tq curve...little late as stated but it holds out well for a bit...

 

Nice job razorlab. The torque is nice and flat for 1200+ rpms. Did you find the S1's better for the autox? Just curious since I figured the S2's would make more up top, but you may not be needing power on the top end. Anyway, again, good job.

 

Congrats on breaking the 400! Now do it for your car

 

Great power for what looks like a very conservative tune!
