i am shooting for 400 to 450 on pump gas. i was wondering if it be safe? setup is
lasky racing blueprint and assembly b16b 83mm gsr crank
full-race prosteet kit gt30r .82 ar
hondata s300
going to get Evans tuning to tune it
rc 1000cc
walbro 255 high pressure

 

Pretty much the same setup I'm running. I make that kind of power on pump running 17psi.

 

my buddies has 454whp on Pump ran 11.0 - safe

My car makes 400tq but I've seen it hit 418 on the dyno before. Clutch seemed to hold it fine. No slipping so far and i'm about 5000 miles into it with at least 20 or so launches at 8k on slicks.

 

with a solid motor build and a great tuner like Jeff you can hit 480-500 whp on pump, usually at least 460-480 safely

Maybe for the guys running GT4088R's and PT67's, but to push 500 WHP on pump gas out of a 30R is very, very unrealistic

x2 and without knowing the compression of the engine and what you consider "pump gas" its even more unrealistic...

 

weve done it numerous times with 35r's and 67's. made 505 on a 67 on 93 (i dont recommend doing this)

400-450 is where i like to stop. the 57 trims we usually make around 420-430 pretty safely and easy on 93

oops my bad...didn't think about the turbo, I was talking about a 35r haha. With a decent tune, 480 whp out of a 35r is def possible on 93 octane. Of course once your at 450, there really isn't any need to increase HP more for the street bc you won't be able to tell the difference lol

How do you usually decide where exactly to stop when tuning on pump? Whats the usual limit on a 3071 and 3076?

 

You almost nailed it. It made 490 whp.

 

175wtq/liter

 

making that power on a built moto using pump is possible as long as your compression is low...say 9:1 or lower...
