sohc motor is it safe to run -10 psi witha professional tunning it , but it wont be on a dyno just a tunner guy and all his stuff hooked up to the engine tunning it , it should be safe right, or is 8 psi all i can go

 

There is a sticky at the top of the turbo nitrous thread that addresses this.

took the words right out of my fingers..........basically the post is telling you to not base it on psi and base it on a certaint additional power level, in this case 50%. reason being is that all turbo's supply different air flow rates(cfm). for instance a t25 at 10psi will not flow nearly as much air as a t3 at 10psi generally speaking. for the most part sohc 1.6l engines have been known to make 200whp on stock internals and a good tune reliably.

 

so many guys have yelled in my face because they think d-series cant make over 150hp

 

lets see.... um, none. lol

 

Why would they yell in your face? D-series can easily make over 150...very easily. And I'll add that it can be very reliable also.

 

Because they think that nawz stickers are a safer way to add hp

 

morons, haha. I'll have a dyno sheet to prove that wrong fairly soon. And that dyno reading will have been taken after 7 months of boosting

 

Because they got suckered into buying a B series.

 

let me dig up the link.. its pretty funny
