does the manifold increase performance?

Just the manifold? Nothing noticable.

3rd February 2009, 00:25

it should do with a full exhaust system i think.

it will increase performance but with just manifold ytou would not notice alot, a full exhaust would compliment it nicely and give good gains, i gained 13.3 bhp from a manifold and full exhaust on my mk1 vtr and a good difference in response too

if your going to get a manifold look into a full exhaust if you havent all ready got one

hope this helps mate

the simple answer is that a good performance manifold will make a big difference. Most of the tuning of exhaust gases is done here. The remainder of the exhaust routes the gases, silences the noise and therefore robs the power

you gained 13.3bhp with just an exhaust sysem and a manifold? i think someones not telling the truth, got an RR graph to prove? because that figure seems very very high, normally i would of expected 4-6bhp.

Can be done dude, although I would of though he had an induction too. If you search for 'Snewham', he had a 1.1 60bhp standard, RR'd at 75.8bhp(something like that anyway) with supersprint 4-2-1, race centre and magnum backbox iirc. Also had a green filter as well I think. Still a bloody good result though

yep i gained that, all i had on my car was an open filter, raceland manifold and supersprint race system less the silencer, and it had just had a full service a week before and it made 103.1bhp on the rolling road with graph to proove, so i put wrong figure down in my first post lol but was only off by 0.2bhp haha

it made 75.5bhp atw and 135.6nm which i think is like 101 or 102 ftlb of torque

was a good figure made i was only expectin 100bhp if that, but still all rollers are different aswell, but this output would have only been a few bhp off maybe if it was offcause it seems farily reasonable

i could get the graph on here if you want but i dont know how lol

26% increase in power just by breathing mods?

LOL, thats what I was thinking. But he had dyno print to prove and was when there was a group RR from here somewhere so.....Not saying it was accurate just seemed a bloody big increase

sounds like it was run in 1st gear
