Someone else will have to chime in, I've only played with rhd cars so no such issue exsists

 

My shorty manifold is similar to Turblown's and there is good clearance on the AC lines.

 

Any updates on this?

 

Can't wait to see more results. Great stuff!

 

Its going to be a while on this car.. So I am going to do it on another car( our 9180 FC, waiting for new clutch now )

 

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.

 

This is frustrating. I just went itb's and standalone.... now I want to make a plenum and a custom exhaust manifold so I can run one of these bad boys along with it.

 

Is the actuator really worth the extra money?

 

When the supplied low boost canister can only do 11lbs pounds with duty cycle maxed on the boost controller i would say yes it is.

Either that or order another but higher psi Borg Warner canister.

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.

 

Can we see the power and torque graph

 

I'm sold on the 8374, thank God I didn't go for the GT35 I had in mind.

 

This car, and the other one are being remotely tuned on the street. I believe both will see the dyno when finished.

 

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?

 

Internal bore is different. 70 vs 74mm turbine wheels. Everything else is the same.

 

good choice, you won't regret it - EFR 8374 is THAT good

 

We will be updating our efr iwg turbo systems very soon!

 

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.

 

Not sure there are a lot of folks with 600hp 13b's on pump and water. I highly doubt 600 on any 8374. Maybe on the 9180. Strictly e85 if you're not into rebuilding a lot, I think.

 

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.

 

Impressive, but I don't know how they sleep at night.

 

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.

 

Sure, here...

That's with a 9180...
And that's great. But, you probably couldn't pay me to push that power on a pump 13b.
If you're on that tip then god speed, sir.

 

He had earlier results on a fresher motor and different turbo:
