I know little about turbos, but in talking with Brian there's no doubt in my military mind that he does! The man can make $hit happen.

 

I am pretty close to having this thing dialed in perfrect or as close to perfect as "I" can get it. I am now hitting 15 psi by 4K rpms. It feels pretty good but think it still needs a little more fine tuning. As of right now no complaints she goes pretty good and I can tell there is more potential there I just gotta work with the fuel a bit more.

 

Hey I got things worked out, my TB was not working properly. I wired open those outbaord flaps and now this thing screams. It builds boost in no time and I climb RPMs very quickly. This turbo rocks Thanks Bryan!

 

i think 60-1 is useless for a hybrid. it will suck FAR more than it can blow...

just get your turbine clipped and you should be in the 340 ballpark

 

not if you bore out the exhuast housing and stick an o or p trim in there

 

yeah my stage IV is a p trim

 

true. overlooked that.

but is it really worth all the machine work? if you're gonna go that route, why not just get a big turbo?

 

Sometimes, sometimes not. To be honest I've never seen a dyno from a turbo FC sporting a hybrid with a bored out exhuast housing/larger exhuast wheel. If someone is just looking for 350rwhp, I think a h3 compressor wheel with an o-trim could get you there.

 

super h and a clipped wheel should get you pretty close.

the hot side is only good for 300ish, so why stick a 60-1 capable of 550+ hp on there? it's just extra weight and lag time.

 

i am shooting for 370rwhp with my hybrid.

"All that machine work" didn't really matter much for me, I just handed over the cash It did take a lot of weight off the turbo, though.

The O-trim has been tried before. BLUE TII had one in his car and it was boosting unassisted to ~20psi and then his popoff valve was activated. O-trim is too restrictive for a rotary, I think. I believe BLUE TII had positive manifold pressure at a 70mph cruise. Maybe it has to do with the compressor choice as well?

I chose the hybrid because I didn't have to spend $$$ on a wastegate, a manifold, oil/coolant lines, and a downpipe.

 

I hear ya $150FC anything more than a hybrid can put out is prolly gonna cut down on its streetability anyway. Not to mention the coin and hassle that comes with these other turbos. I like plug and play or bolt on performance. I hate fabricating and such. Besides my hybrid is making awsome power. Especially considering I am only running a SAFC and a stock port motor

 

Actually, I am running the clipped "P" trim now and my boost creep is WORSE than I had worked it down to on the "O" trim.

However, this is probably due to the fact that the exhaust manifold is now totally divided again (like stock) whereas, it had been combined in the WG adapter pipe w/ the "O" trim".

And it looked like Rob reshaped/extended the closing on my primary ports on this replacement engine.

Not to mention I couldn't help doing a little more flow work since the engine was out of the car (pinned the manifolds and flowed the TB plates/shafts.)

Plus the engine has higher overall flow from the larger exhaust wheel.

The "P" trim boost response does not seem much worse than "O" trim. I just start getting boost @ 1,500rpm, 3-4psi by 2,000rpm, 8psi by 2,500rpm, 10psi by 3,000 and full 17psi (wategated) ~3,500rpm. Creep sets in ~6,500rpm. I am sure it will be better once it is tuned- I am running PIG rich in the higher boosts.


I guess I am just going to add mufflers untill the boost creep goes away from exhaust restriction at this point...

you're right about that.. i was looking at the $800 price tag of the hybrid and thinking it wasn't a good deal cuz a 60-1, .96 a/r p-trim is only $600 new.

but then the manifold, wastegate, exhaust mods, oil lines, etc. etc...it all adds up.

so it may be the best way to go for the money then. i'm just about ready to toss my hybrid for a more. umm robust hair dryer. i think i'll actually end up with something quite a bit bigger, but i've got a new way to look at the hybrid situation.

 

Can you clarify that? Have you removed the external wastegate?

 

I still have the 60mm external wastegate.

I added a stainless divider that fits into the rear of the turbo where the WG holes are and all the way up the stainless elbow to the the WG valve.

So when the WG is shut the pulses from the front and rear rotor do not mix (like stock) and when it is open they will just flow into the atmosphere instead of reverting into the other runner (since it is path of least resistance). It is just fully divided again. I will post pics tomorrow...
