Sizes of external wastegates

[Sydneykid]

Simple question, how big is yours?

I am doing a survey for an article and I really need some help..........

1. how much boost are you running

2. how many rwkw

3. how big is your wastegate

I don't care too much what brand of wastegate it is, but you can tell me if you like.

Thanks for your help.

my previous setup on the rb20

15psi, 234rwkw, 45 mm turbosmart gate

[Roy]

Sorry.. a little off topic, but if someone can give me a wiring diagram or help me wire up my resistor pack and GTR injectors then ill be able to answer the "how much power" at 1.2bar.

[Steve]

40mm, 1.7bar, 309rwkw but getting choked by the exhaust. 285rwkw at 1.2bar.

[DR30RS]

Turbosmart 45mm,250 rwkw @ 1.3bar

[Sydneykid]

Sorry Roy, I can't help you, I have never used GTR injectors in a GTST. We always use Series V RX7 Turbo injectors, they are high impedance 550 cc's.

Maybe someone else can though ................

[Sydneykid]

Might as well stick Ben's R34 in here...........

1. how much boost are you running - 20 psi

2. how many rwkw - 290 rwkw

3. how big is your wastegate - Turbosmart 45 mm Progate

Next............

Thank you to the guys who have put up the 5 sets of data so far, I really would like another 10 or so. So if you know of anybody with an external wastegate on an RB, please give them a push to post their numbers.

Thanks

I would like a few more to give a decent sample, so prod your mates and get them to post theirs. PM me if you don't want others to know what you are running.

255kw @ 1.0bar on a 35mm turbosmart ultragate. Should be trying 1.2bar soon... I'll let you know.

sydney kid, this is simply an idea i have, but yet to get any really tech imput on this. im thinking if it would be possible to run say 3 35 mm wastegates. which they open at different times. the only benefit ive been able to think of from this is simply if you want to run high and low boost you might be able to control the boost at low level smoother. just still its simply an idea not sure of the real benefits of problems that could come from this. or how to set up. sorry to jump onto your thread thought it might be worth mentioning here.

r32 gtr, hks t51 turbo, hks 48mm wastegate, 12 psi, 228rwkw. needs more boost obviously.

[MattyB]

225 rwkw 12 psi (need aftermarket management to go higher in boost) internal wastegate. what ever size that is.

[Sydneykid]

Hi guys,, I have received 10 replies for Skylines so far, I'd like another 10 or so. Just to confirm the formula. Then I will publish the findings and the application table, should be interesting.
