Besides turbo is there a site that tells how much horsepower gains you get from upgrades like pulleys, intakes, spark plugs, exhaust kits, etc. just trying to price and add up hp gains before I purchase any parts...

it would be differnt from each application, and im sure people would like to see dyno charts. not just theories. at least i would.

Don't fall for the "PEEP" idea that an intake will give you 4hp, the header will give you 5hp and an exhaust will give another 4hp.... that makes a 13hp increase right??

NOT true, as one of the tuner magazines recently found out on an xB.... With a header, intake and exhaust and testing after each installation it doesn't add up. I think they added less than 8hp for over $1000 in parts. I don't remember the mag, I threw it away in disgust! Search farther down the posts to find the thread.

ken

intake- 4hp
headers- 1hp
exhaust- 1hp (i think it was an axle back)

i don't know about u guys...but i have K&N typhoon on my xB and it kick ___~ i definitely feel the extra push and the exhaust helps too.

here's the DYNO for the xB from K&N .. 8.5HP gain from the intake!

5.6hp gain - and these dyno runs were done on the same day, on the same car, 1 hour apart :P

- I really gotta coordinate with Adrian about the Scion Evo Dyno Day BBQ... in fact i'm gonna PM him right now, there are some summertime weekends coming up where there are no shows that would be perfect!

manifold back system alone!! No intake or anything else. well, 18inch rims.

i picked up this car last week definatly slow but what do u expect, i too am looking at things to throw some pep in my pimp but nothing will increase the horsepower that much.

the typhoon intake your talking about is 2 piece, i wanna pick that one up but is it the same kit as the one sold on hopupracing.com?

i'm not sure.... i got mine directly from K&N...but contact Nilo or Adrian @ SST...they will quote you. And for clarification it's actually a one piece intake pipe with filter cone w/ sleeve.

personally...it's the best "working" intake out there besides injen. U do feel the extra HP...

Who cares about hp? It's torque that you want and that will make a difference. I'd look around for what items gives you the most added torque, and hp will of course go up slightly with those items as well.

Didn't you notice tha torque increase on my dyno sheet? Its the same increase as the HP. :D

if you're looking for bang for buck. Just hold out until someone makes a good quality high HP turbo, or wait for a company to finish some motor swap kits. Everything else in NOT worth the $$ in my opinion.
