Default N/A to approx. 300HP? How?

Correct me if I am wrong, but didn't the British Touring Car Championships have cars that were putting out about 300HP on 2000cc engines N/A? How do they do that? Apart from engine management, ported everything, balanced everything, better cams, better pistons, better valvetrain components, lighter engine parts, better ignition sustems, better breathing, what else is there to do to get better output from an N/A car?

you prolly just named all of it. high azz compression with race fuel.

NBE (Neil Brown Engineering) used to modify the motors for Honda. I'm not sure which company is currently contracted to develop/maintain those motors. I think its in one of the mags this month.. some Italian company I believe

Don't even think about buying one $$$$

ps. Have you ever seen the intakes on those cars when the hood is popped open ?? Looks something like an F18 ram intake. HUGE

u have basically eliminated almost everything that makes an N/A produce power. other than that..make your car lighter.

Actually, whatI think is really cool is the sequential trnsmission that they have. Much like the M3 SMG II. Has anyone switched to one of these trannys?

Ya... I think they managed to squeeze out 310-320hp at the crank.
The rules said that they couldn't spin the motor more than 8500 rpm.

not feeling that

i have a golden eagle block 3/4" deck plate, a big crank, 10k rpms.. thats all i'm gonna tell you some itb's, some big cams and custom side exit header i don't think i'll be that far off.....

Keep "feeling" things and you will go blind young man...

Your argument walks two paths to a similar destination... yet not.

I may have misread, but the cars he is refering to have nothing, but nothing to due with a quarter mile pass...

yea i know they were road race cars thats why i said "although for drag"....and my vision is fine maybe one conconsion too many got things a little blurry but... .....i just don't like the idea of the payn block...they don't and won't allow a custom head in competetion so why should they allow these blocks...but bottom line is it's the same deal as full tube chasis, center drive and sequential trannys... they don't belong in the all motor class...which is supposed to be the door slammer class of import racing...not the "outlaw" $50k+ monsters that are going to be coming out next season....hopefully the sanctioning bodies will realize that they are going to need a new unlimited/outlaw class soon.

Can't use a deck plate in BTCC. Hondas motor was a destroked Prelude motor
160 NA hp/liter with an 8500 rpm redline.

those cars rev to a gazillion rpm and readily maintain torque at that high prm which equates to very high peak HP. I've dyno'd a german destroked 2.2 liter M3 sold by BMW, it pushed 291hp at the wheels @ around 10,500 RPM. the motor revved to 13,200 rpm if I remember.

For the honda accords in btcc, they chop the lower non vtec lobes fromt he cams and put it thru some chilling process, John Grudynski does that all the time, as a matter of fact, thats the first thing he told me about when I showed him my Toda killers.

the answer to this post-

btcc limits you to 300brake hp...so account for a 20% driveline loss with those sequential xtrac type trannies and your @ 240 whp...not out of this world, especially with seemingly bottomless pockets funding your project...

Did you read the specs ? IMO approx 275 whp (maybe more) @ 8300 rpm from
the NA 2 liter. There was no limit on hp. Amazing what a big budget can do.

That is my question....let me rephrase. Without any monetary budget limit. What else are they doing to achieve such an amount of HP at 8300 which implies that they have a tremedous amount of torque to generate this power at a relatively low RPM.
