100kw @ wheels from NB8A

hi all, just wanting to know what kinda stuff u would do to an NB8a to gain 100kw at the wheels?
would full exhaust, CAI do the trick or would u require computer and cams also?
maybe just exhaust cai and fuel computer??
anyway any help would be great

All that plus headwork, cams, better valve springs and upping the compression by a minimum of half a point at least through shaving the head. Zorst, CAI and computer will maybe get you 5-8rwkw.....that's all.

i am currently putting out 87kw @ the wheels with a k&n pannel and chopped std air box, 2.25 dodgey press bent cat back...std cat.....looking at doing a full mandrel exhaust and mania cai....what u reckon i would b looking at power wise for that??

You might get another couple, up to ninety I guess but by the sound of it the zorst is already working because I thought the 98/00s only did around 82 stock rwkw? What was your baseline dyno pre mods and which type of dyno did the 87 show up on? All my comparisons are to shootouts.

I just checked the dyno posts and 75 stock would be normal so it sounds like you are already laughing - another freak NB8A!

I got 86.5KW at the wheels on a standard NB8A on a Dyno in Sydney. Same day we dyno'd a Supercharged 10AE and it had 110KW at the wheels from memory. It was a bolt on from the USA and around 3K..

Cheers

At a dyno day a few months back, an NB8A with short ram CAI, extractors, and exhaust got 82.5 rwkw.

I can't really see how you'd get 87rwkw before any decent mods were made. Different dynos, different days, but 5rwkw is a pretty big gap.

You'd need extractors, proper exhaust and CAI, aftermarket ECU (piggyback), and probably cams.

who is the dude that go 20wkw from 805c's and microtech? - do that and extractors. if you get a tune on 100ron it should help a little.

You are not going to get 100rwkw naturally aspirated (UNLESS you spend big, and then it would be cheaper to go a turbo).

Why 100kw? I know its such a nice number but...

True and true. This is about what my race car would put out I think. Perhaps it has a shade more. It ain't really friendly on the street and the build cost about $6K + computer.

Most cars were 0.5-1.00KW less. I could only put the difference down to a zorst mod.

Not an NB8A but I thought it would be an interesting aside. A peson I know got 90rwkw out of his NA6, with Mania CAI, headers (I don't know the brand), 2.25\" X-Force exhaust, and a Wolf 3D computer.

Everything else is standard (according to him).

when you say 805c's, what are you talking about ?
injectors??

bigger injectors will have NO benefit on a naturally aspirated engine.

ah, ok cams. that makes more sense. have heard good things about those tighe cams on the 1.8.

well col, you've now got 1 more person to help and give advice with your turbo install. good for you eh ? :mrgreen:

Very much not true. Injectors should be sized to the engines requirements. At 120rwkw NA, I had to use larger injectors and more rail pressure as I was well above the original injectors operating range. 805 grinds from Tighe are the ones they recommend using with a stock ECU. If you really want more power, they have plenty of other grinds but you will need to alter timing and fueling delivery. I've had 805s, 877s and a modified 879 grind (lotus ford) which are very serious cams requiring lotsof mods to fit. They will increase power but also $/kw disroportionately. The 805s are a sensible cam choice.
