and yes it is Ball Bearing.

Hard to visualize it myself that this thing will hit 400+ whp on the renesis, but it looks to be a great turbo to hit near it and be quick spooling.

 

Interesting for sure

 

Garrett claims it flows about the same air as a GT3582R, which has already made over 400rwhp... So as long as the compressor map doesn't lie, it will do it..

 

So how is just a turbo alone going to give you these figures?

 

^

 

Love to see the numbers on this.

 

nothing draws in the clueless moths faster than a 400+rwhp light source

 

A renny can make over 400WHP but can it make 400WHP reliably for any decent amount of time without going kaboom.

 

Seems to have been put in the too hard basket . Much easier to do it with an older generation rotary so there is no real reason to do it other than to say "we did it" .

 

Isn't that how everything is? lol

 

and spent 2x+ more proving it

 

lets see this happen

400 rwhp renny .... id be happy with a 300 rwhp reliable renny

 

Subscribing.

MSP=MazdaSpeed Protege?

Or 13B-MSP?

anymore details on said 450whp road race car?

 

interested.

 

i have two questions, first ,This will be my first winter with my mazda RX8. What kind of tires do Rx8 drivers get for the winter that will mantain a cool look? secondly whats the best turbo up grade for my car?

 

wrong spot to post your question. Please post question in the lounge

 

ok thanks

 

bump, I can see the physically smaller compressor wheel helping it spool up a bit faster, but question if it will make much difference since it will still have a GT35R hot side which is going to spool up noticeably later (in comparison to the smaller options) regardless IMO

feedback?

 

Team is right. When the ambient gets below 80F, I have a difficult time keeping my oil temps at or above 180F while on the road. Around town--no problem, but on the road my ect and oil temps like to stay at about 170F. When it is 40 degrees outside I have to add oil cooler blockers.
I have the mazmart 180F coolant thermostat and I am running 50/50 coolant.
Its constant work. Above 95F ambient the systems need a little help--fans etc. Below 80F and you have too much.
Then driving it hard--changes things again.

 

Posted in the wrong thread I think, lol

 

Good point - but what AR turbine housing are we talking about ? I assume the 0.63 option would spool up very well but what would be the limit of that housing ?

 

damn!

 

The power potential should be the same as GT3582R, maybe slightly less since it has a smaller compressor housing, hard to say exactly.

A GTX3582R will make more midrange power, but probably the same top end as a GTX3576R & GT3582R.

You are correct the limiting factor is the turbine housing/wheel. A T4 1.06 GT35R housing is about the same as .84 T4 P trim housing. On the Rx-7s we mate the P trim turbine wheel to the GT35R( called TD61) and it makes roughly 50 more rwhp over the standard GT35R.

This turbo idea was considering limitless funds( fastest spooling 400rwhp turbo for sure)

Personally I would run a standard GT35R in a 1.06 Tial housing.
That is what our low mount kit is setup for( although it will fit GT30R stuff is requested).

 

I'm more interested in a fast spool and low-mid range power than top end for autox use.

The FD3 v-mount setup I posted earlier is running a Precision with a .78 TS on a stock block engine that is probably the equivalent of a GTX3071R. It falls off on the top end due to the hotside limitation, but the low-mid acceleration and response is pretty awesome. This thing squirts out of the corners with amazing acceleration.

 

I would use a GTX3076R with the biggest hot-side available, open dump 60mm waste-gate, and a 4" exhaust system. Manifold needs to aim all flow at wastegate too( basically how are low mount is made).

Obviously you will need a engine consisting of all brand new parts, and built correctly. This is the biggest key to fast spool.

Although if you set your power goals lower, a GTX3071R would spool faster, and on a race gas only tune & higher boost maybe make 350rwhp...
