300whp Goal on DD dyno PLEASE HELP
A friend of mine dynoed 263whp/260 tq. on a DD dyno on stock boost. His power mods are: Borla Turboback, UTEC, HKS 264/272, and HKS cam gears, fuel pump. He said he wants to reach 300whp on 91 octane and I told him he should turn the boost up to about 21psi and he'd probably be almost there, somewhere in the 280's. But then he was saying he doesn't want to turn the boost up because it'll mess up his A/F ratios and risk "blowing up his engine" and saying he's already maxing the stock injectors and gets consistent fuel cut. I know a lot of you guys are near 300whp on 91 octane at about 21psi so basically he's full of it. I know he's not maxing the stock injectors and I know there's a lot of evo's out there SAFELY pushing to 21-22psi w/o fuel cut. Can I get some advice on what to tell him (you guys know a lot more than me) and how he can accomplish his goal of 300whp on the stock turbo, injectors, and FMIC.
thanks
thanks

Hmmm, it sounds like a "run lean" condition on top of 91 crap-tane would be a bad combo with higher boost. I wouldn't chance it until you've got the fuel supply situation worked out. Even then you have to be concerned about knock on the low octane fuel. Maybe he should look at water injection. I bet he could easily crank up the boost on 91 octane with something like WI to quell the knock activity.

Check out this thread by Malibu Jack. It covers some important info regarding boost levels and injector capacity.

Intake, Turboback, and AEM EMS tuned conservatively will give you 300 whp.
Edit: Forgot to add, if he's got Cams and Cam Gears he would be closer to 340 whp with the EMS.
