im a newbie to turbos.. just wondering if there is a difference in turbocharging a vtec engine vs. a non vtec.. thanks

 

you tipically need a smaller turbo because you wont push as much air (vtec motors rev very high) and your tranny selection will be influenced by how high you plan on reving also

 

vtec heads flow better = more power pound for pound

 

tunning is different since there is no switch to high cam lobe on the nono vtec.. Much simpler to tune.

 

search for some dyno threads, you'll see most non vtec dyno plots w/o any head work fall off on top end, while the vtec dyno plots increase all the way to 8k+

 

anywhere from 100 and up horsepower difference, and thats on a vtec head, just with the vtec unhooked

 

What the hell are you talking about?

?? couldn't of said it better my-self

 

Back to answer the origonal ?, the VTEC does pull and if tuned properly will make power all the way to and sometimes over 8k. The feeling that I can compare my turbo GS-R to is riding my old Suzuki 250R Quadracer. Boost comes on full at about the same point as VTEC is being engauged, it feels like a powerband from the 2 stroke. But thats just my .02.

 

i love that kick out of two strokes :drool:

 

SI{nce you said you were a n00b. The cars with Vtec have higher compression which mean s the tune has to be very good. High compression motors are more prone to detonation adn detonate easier. So a LS is less prone to detonation, but won't make as much power per LB of boost as the GSR does...or any VTEC vs. NOn-V
