450Rwkw On Pump 98

[cycocepta]

Just wanna know has anybody got a proven rb26/30 combo with approximately 400 - 450rwkw on pump with good street ability using a single turbo on the hotside, with power around 3k - 4k

So basically chasing turbo types using 9.0 compression ratio, cams in engine and whether head work was done.

I spent a few seconds doing a search for you. I hope you find the answers you need here.

thanks

do some decent porting of the head and it will make it easier. We had a T78 on an RB26 and depending on the dyno it made either 460rwkw or 400rwkw lol

All we cared about was that it ran 130mph+ on 98 pump fuel so the dyno figures didnt really matter. It now makes 485rwkw on E85 and time will tell what mph and et it runs now

Checked out that 400kw link but doesn't really get into pump 98 combos,everybody has jumped on e85 band wagon.

So please guys after some 98 premium combos

Looking towards gt4294r to deliver the power and good street response

Large framed turbo and good street response is what everyone wants but physics gets in the way.

If it isn't in that thread then it's probably not going to happen the way you want it.

Is it a silly question to ask why you need that power specific power level?

Not going to happen at 3-4k even on a 30 bottom end

[cycocepta]

Basically the power level is to achieve guarantee high 9 sec pass at calder

Previously had a single cammed rb30 go 10.8 at 126 mph at calder on pump fuel with jatco 3 speed with 3500 convertor and 3.7 in rear

Now have gone twin cam 26 headed rb30 so basically seeing what works for people

Not looking to break any records just want good honest power and not a dyno queen

[cycocepta]

That was with a gt35/82 with 1.06 rear

No lag and killer in the street

400 rwkw is doable with a 35r, car went 130 mph with a manual in an R33

There are good reasons for jumping on that bandwagon, petrol is crap.

Good luck...

Been running around 450rwkw for nearly 50k kms with old TO4Z garret at 1.8bar on 98 and 2.8L, 132mph good drivability but most of the power if after 4k with old tech turbo and 272cams. Better cams would bring power band down

420rwkw on E85, 25psi, in a 1400 kilo car that ran 137mph with a GReddy T78. Used to have very very usable power by 4000rpm

Now making 485rwkw on E85 at 25psi with a Precision 6766 and 1.0 rear. Will tell you Sunday what it runs

Seriously forget the 42 and look into a Precision, Much smaller, much better response and still massive power considering the size of them. They are tiny in comparison.

Hopefully your user name will come true on Sunday

Goodluck buddy

The 42 is a good turbo, it will run well over 550kw, as should your Precision...
