Does anybody know something about the company?

i saw ebay auctions with stock ported manifolds.

on the website http://www.dh-racing.com/ they said, that this manifold will give an extra power of 25 whp.

they said, they build the fastest honda's worldwide.

i think this is a little bit overdressed, but i want to know if this are good parts.

 

i have their crank pulley on my b16,its very nice,rpm's climb quick,never had a problem with it.if i had the money,i would buy their manifold in a second

 

ok i bought the Manifold of the D15B7 and the DH Racing Throttle Body.

Nice to look at:



But it gave only 5-10 hp

 

its a d15, if thats to the ground i'd be in awe

 

yes it was the d15b2 with poor 90 hp... now its the d15b7 with 101 hp... and after the modifications it has to be about 110 hp.

in the next step i will add the mini me. 130-140 hp..

we will see
