As soon as the engine is back together on our roadcourse car I am doing an entire dyno comparison days( back to back tests between 7670, 8374, 9180, iwg vs ewg, shortly vs long etc). I have all of the turbos, and manifolds finished sitting here ready for it.
Rotors are on their way back from balancing on the engine...

A lot of people have been asking for pump gas results in terms of boost response.
Here is an FD I have remotely tuned. It is on pump gas with a large street port. In my experience porting hurts response. The new twinport turbosmart IWG actuator is being added and this car will be going to 30psi with water injection.

Keep in mind we got to 27 psi reliabily with medium can on Shawns 8374 iwg. This was with 7 turns of preload on the actuator however. We are waiting on the clutch to arrive and we will hop back on and thourghly test all settings and configurations.

Here is another forum member's 8374 system on pump gas with a large street port. OE BW medium actuator.
Details are all in the chart, you can follow the blue trace to show where the engine was. Bottom near .01 TPS @ 2767RPMs is the start of the action. I ended the trace at the 99.60 WOT.

Just curious, is the .92 A/R housing on a 7670, will that fit on a 8374? are they the same housing? or are they different? Looking to possibly swap housing on two turbo's. anyone know?

Hopefully we start to see some more results from these as more of them are installed. I'd really love to see if the prediction on the first page of almost 600whp is actually possible on this IWG turbo, especially since IIRC that is near the theoretical upper limit of this turbo on a rotary. I'd also like to see how the IWG responds above 30psi.
600whp on pump gas(with water injection) and this kind of response would make for a very fun street car.

I believe Rice Racing has done it a few times, 600 on pump and water that is. IIRC, Raceonly, who has posted in this thread, did 700+ on pump and water, with a 9180 no less.

You realise water injection isn't some kind of voodoo magic right? There are plenty of SAE papers and numerous other academic papers on it.
In shitbox T2 block based context green brothers went to something like 750rwhp (?) on a street driven extend port 13b on water alone before going to water meth running a basic pre turbo atomiser. Thing did a lot of running too.
If you are worried about engine longevity I think the oil change frequency and oil thinning of an alcohol fueled cars are of greater risk than running WI for a similar power target.
