Well it was until recently, but the 2 K20's I race against have now also been stroked (one to 2.2 on ITB's, and the other possibly to 2.3) so I think my next race will be hard work
will a more aggressive cam not reach its peak at a higher rpm say if the duration is longer as it would need more volumetric pressure to get the best from it
Kris i want your engine, it is my dream to have vtec with ITB's
I need to come watch one of your races just hear that thing go!
Look forward to reading your next race report mate!
O GOOD LUCK too!
Yes you are right there, but i have read time & time agen that the EK9/DC2 cam's can make power upto 9000rpm but in my case they start droping off about 8650rpm
So companys that state there cams to make power up to 9000-9500rpm i would like to see graphs to prove!
So this is why i say i will wait & see how it it dose on the dyno befor i state i will be reving too 9000rpm!
Yea shouldnt believe everything you read,nothing beats personal experience,hope your build goes well bud
Cheers mate!
Im sure it will be just fine as "WILL" is doing the build & the tuning!
I gonna assemble most of it myself hopefully but will get martin treacy to hone,PnP,balance and tune ect....
I am more than capable of doing the build myself (I have done many before) but Willâs is offering a VERY competitive price & then I know for a FACT that it will be right!
Will is a friend of mine anyway & I will prob do most of it with him, itâs just I trust his work more than my own!
you should talk to Performance auto works. They built kris dunlop 1800 with 250 bhp @ around 9000 rpm.
Jimbob.......yeah it sounds great especially in the car, but the sound gets lost on camera so any footage we have just doesnt do it justice. I'f I can afford it, the last 3 races are at Snetterton, Mallory and Brands so pop along if your close enough
With regards the engine, its making peek power around 8800rpm so no need to rev the guts out of it and makes it a little more reliable!
Jimbob: I think you are pretty close with what you are saying about stock B18 cams. With my eCtune setup they make peak power at a true 8200rpm, holding well to 8400rpm & with the limiter at 8700rpm (9200 on the rev counter). Swinging the cam timing could extend that slightly at the expense of low end torque i suppose.... I personally dont think a road B18 really needs to rev harder than that anyhow.
Not much point unless some investment has been made in making sure the bottom end is built & capable of withstanding it for sure
Yep I am he
Performance Autoworks are based in Fairford just outside Cirencester and come highly recommended by anyone that uses them. Richy built my engine from scratch and did all the headwork himself and has built a cracking motor. I've started 9 races this season and finished all 9 aswell as 9 qualifying sessions plus test days, so that says a lot for his/their workmanship on a motor that is at the limit all the time!
look forward to yours jimbob
