Power is nothing without control:

 

are we taking bets on how long before the constricted wastegate piping results in cracks?

since that turbine housing is stainless steel was thinking that; assuming there’s hood clearance, coming directly tangential off the turbine housing with an elbow to place the WG horizontally above it with the discharge aimed toward the downpipe would have allowed a flex bellows in there in addition to also being highly favored for flow diversion. The electronic actuator also wouldn’t be buried down there if the furnace zone.

props to him on the Garrett G-series turbo selection though; proved to be all and even more than I expected it to be. Would love to see a G35-900/1050 with 1.06 A/R T4 comparison to an EFR. Or even a G30-900. Still flying way under the radar on this forum.

thought Turbosmart had intended to offer a butterfly-throttle valve version of the electronic WG, but it seems to have gone awol?

teamrx8 im going to be testing the 900 and 1050 back to back on a 2 rotor. probably the c5 next week. Ill obviously document the findings haha

I also am going to redo the egate position. i always knew this manifold design was setup for maximum boost haha. I just never had a turbo this efficient on it. I cant get the 3 rotor under 800 hp in 3rd or 4th gear. a hilarious problem to have

 

why do my cars smoke so much? partially that you see them always warming up in the videos. I do premix 2oz per gallon so i think its on the heavier side. And in the half mile video at the end i had pitting in a used iron i was sold that allowed coolant to get around the coolant seal. had to rebuild the engine and load that area up with silicone haha We shall see how long that holds

 

2oz per gallon is definitely too much. I ran half that and when I'd tear down my engine everything would be liberally coated in premix. I think Klotz Original Techniplate was what I was using last. Everything was nice and clean even feeding 35psi of boost. It didn't have any issues with e85 either.

Also make sure you either have pcv setup or have some serious crank case venting, otherwise you may end up backing up the turbo drain which could cause smoking. If your engines were built with fresh oil seals and the springs were facing the right direction, not much else is gonna cause smoking.

I found a picture of a rotor I pulled out after running 1oz/gal of that stuff after an injector started sticking. You can see how much oil is still on everything with just 1oz/gal

 

been looking at them pretty hard myself with Garrett finally releasing the 1.06 A/R divided T4 housings several weeks ago. It just depends on the power level goal. The 1050 should be good for 700 or maybe a bit more and still be fairly responsive. About the same 350+ whp per rotor range you just did. Those efficiencies out at the upper far right of the map make turbo speed controls a necessity though to avoid blowing past the max limit. It won’t fall off like might be expected on turbos less efficient out there, or not until the wheels start coming apart/off .. so to speak.

Thanks to whomever banned this troll. It might have been entertaining if they could spell words.

Also congrats to @rdahm the videos have been pretty entertaining and it's fun to see how much you've learned in just a few years. It would be fun to see all your cars (including the Insight) compared and contrasted at an autocross or a track day. Plus a stock FD and a stock C5 corvette for reference, if you can find those.

 

Rob, can you tell us more about that WOS starter? I looked at their web page and it looks like they have a 2kw option which seems like it would be similar in power to the banzai upgrade. Is there more to it?

 

I had the banzai one on the 3 rotor and it was solid. but the wosp one is even better. Its not just the power, its the gearing. They said that basically the motor takes less torque to turn so they turn that power into higher speed. I was impressed. Ive seen 330 rpm when it turns over.

 

the Series 2 (2009+) RX8 starter is about the same rpm, at least on the 2-rotor; 2kW and they added an additional tooth to the gear and compensated by offsetting it a bit, yet it still mounts to them all. Made a substantial difference and I think maybe it’s a bolt on for the REW?

 

the ears are all different from FC/FD and Rx8. that being said, not too hard to swap the nose (except maybe S2 Rx8) and/or drill a new hole. i've got an FD starter in my FC turbo, and the bottom ear is longer, and i could drill a new hole (or not, the top hole lines up, and its only 50% of the bolts, but on my car that is like a B-...).

 

ok thanks, seemed like the FD and RX8 both had the long ear, but I was only looking at pictures rather than having them in hand

 

they do, but they aren't the same. its been a while, so i don't recall how exactly

 

… perhaps a DCT trans swap should be considered along with some wider wheels/tires and fender flares

 

Rob sure ha come a long way. Awesome progress here

 

wasn’t particularly impressed with the budget Renesis rebuild series, but yeah, it runs, though am quite sure that a dyno will reflect the choices and work performed accordingly …
.

 

I don't think the renesis rebuild was meant to do anything special. That's why it was a budget rebuild.

It's pretty cool to go from not knowing much at all to now see decent machine work, fuel rails, wiring, extreme tolerance dowel pins, jigs for repeatable work, etc.

But haters gonna hate haha.

 

“haters going to hate”

really? Maybe you spend too much time on youtube 🤔

no, my comments on this forum do demonstrate that I simply express it as I see it; both the good and the not so good, but since you felt the need to go there then let me clarify it directly for you:

a half-hearted job is a half hearted job, there’s no hate in expressing disappointment in another improperly built 170 whp Renesis engine.

especially a hyped up one, possibly because of my personal interest in that particular subject.

I’m sure you’re not any different in that regard, nor anyone else either.
.

 

That's the thing, you say you comment on the good and the bad. You didn't comment on the good. And you went right to the budget build as the "bad".

I'm not sure what you mean by hype. It's a YouTube channel. It's not like it's a shop being hyped telling everyone to go there for rebuilds.

 

The rotary Vette is getting better!

 

meh; neither positive or negative, just indifferent on this one

 

I just can't stand the sound it makes with that exhaust haha

 

It is utterly disgusting haha. its also confusing as it sounds like **** but is making power. Definitely tuning the exhaust next.

 

Hats off for leading the way on what the G-Series turbos can do.
.

 

I just saw the video yesterday of the vette on the dyno. The car is making good power. I see that you went vmic. With a closed hood I beleive they are the best setup.
