450-500HP turbo, Internal or External Gate?

[Bl4cK32]

May have to start a new thread regarding large HP and the way power is delivered, compared to say power figures around 250rwkw and how responsive it feels....

Although, as you say Joel , 300rwkw rb30det feels faster than a 300rwkw rb25det...

Im thinkin of gettin a TD06-19c, mattR had one and made 286rwkw on bp98 and 313rwkw with toulene.....

Decisions decisions.

Dont want to sound like a non believer, but that is great power out of a TD06-19C. Not doubting that figure, but doubt everyone usign that turbo would see that power output...what boost level and did the engine live of was it a case of good whille it lasted?

Dont shoot me, im just curious because i havent seen those figures out of the larger TD06-20g on RB25s

[Bl4cK32]

Dont quote me, but i believe it dropped a valve...may have been due to the toluene....

edit/ sorry Matt if your reading this, i dont like discussing others problems....

In a jap mag there is a 2.2ltr EVO8 that made 373rwkw using a HKS 3037ProS.

 

Sounds a little optimistic.

 

I'll try to get a scan of it. Its in jap writing but.

I'd like to see that !

What ever turbo you choose, the first factor is how much lbs/min the compressor is going to push out. Then probably turbine restrictions, be it in the (too small) exhaust housing or (std) exhaust manifold.

The 20G wheel is roughly the same size as a HKS 2835R wheel - max is ~45lbs/min so around 450 flywheel hp.

The 25G wheel is roughly the same as the HKS 3037S - max is ~55lbs/min so around 550 flywheel hp.

The 19C wheel is alot smaller than the 20G wheel and a very different design. Interesting quote on chassis dyno kw for this compressor.

Hey guys, according to matt, 286 at 25psi with a 1.4mm head gasket.

His engine failure was caused by a stalled injector or somethin like that...s

Internal wastegates are for girls, real men use external gates

Anyone had any bad experiances with t4/t3s on rb20s? or wat power they were able to make?

I've bought one with hks high mount manifold n gate n was just after a bit of advise.

me boss made 312 rwkw with a TD06 19C on a rb25det sloted into a 32 pulled 11.6 (I think) the turbo is up for sale in our shop at the moment for $1,250 cheap

enrico i was pulled over and defected the other week. the highway patrol went all over my car including the turbo which is HKS GTRS. I had no heat shield so the turbo was clearly visable, i told him it was all standard. He didnt have a clue and just got me for the rest of the stupid stuff...

Have a read through the "Top RB20 club, 260rwkw " thread as there is a lot of good info and results from various RB20 configurations.

As a comparison I have a T3/T4 hybrid type turbo with internal gate and make around 235rwkw at around 16psi which is seen just before 4,000rpm in 4th on a dyno.

Besides the turbo/manifold/gate what else do you have to complement it?

[drifted4door]

ive got a Wolf ecu 4 it, AVCR, 3" exhaust, front mount, bosh pump, 550 injectors n looking at some tomie cams. Wat do you think would be possible?

Prolly gettin parts fitted bout a month or two........hopefully!
