great stuff .
300whp Greddy here we come

 

Hopefully more than 300whp, I am going to use a meth kit. So I dont see why it would be a problem to reach it.

 

whoa, this looks like it has a ton of potential. Can't wait to see updates on this.

 

I ported the turbine housing to its max and also ported the wastegate to the max. I really took out a lot of material on the wastegate. The WG should flow twiced as much as it did before. I would take pictures but that gives away all the secrets :D.

The water system with all the lines and fittings has been taken care of (banjo fittings, tubes, crush rings ect.). I will have to make a custom oil supply fitting, but isn't a problem.

I am thinking about replacing the turbine wheel as well, maybe with one with lesser blades to open up flow even more. I will have to sit down and do some figuring. Then all the rotatating assembly will be new and no reman parts other than the end housings are used.

 

Man I can't wait to get this badboy back!!! My 8 will be ready to go!

 

You aren't kidding, that is a product that could sell like freaking hotcakes around here. If my MM upgrade falls through, which I will wait about 2 months more to see if it comes through, then I'll take one of these in a heartbeat.

 

looks interesting

 

I'm down as long as its more reliable than stock.

 

I wouldn't build anything that wouldn't last. The water cooled center is the key if you want life out of any turbocharger. The mitsubishi in my GMC Syclone was stock and it lasted 150K before I pulled it out and put a 50 trim in it. When I pulled it out, it was still dry as a bone... The turbo in my GMC Typhoon has 140K on it and it is the original turbo that came from GM. They are both Mitsubishi water cooled turbochargers and have zero issues. I also have a TD06/50 trim hybrid in my 323 GTX and in 4 years of 17-22 psi of boost, zero problems! I really like mitsubishi turbos. They are strong when done right.

Can't wait for more news!

 

this will be my next mod hopefully very soon...good job!

 

great news for greddy owners!

 

Excellent....

Are my posted flowmaps the correct ones?

Those are some RARE trucks Bryan, thats awesome that you have both. Hell one just sold for about $40k i believe and it was a brand new 1993 model.

 

They are rare. I got a pretty good deal on the Sy and I traded a hopped up 87 Grand National for the 93 Ty. They are definately fun to drive.

 

My brother used to own a Typhoon in the mid 90s. That thing was a beast!

 

You are correct sir. Thanks for posting them up.

 

the very last Typhoon ever made was just recently hauled out of storage by GM and sold at Auction

Good! now GM can avoid bankruptancy.

 

I can get my hands on 1991 Syclone #0001. He wanted my white FD in trade for it. I ought to call him back up and make the swap.

 

Here are the compressor wheel comparisons between the 18G and the 60-1 incase you would like to know.

 

Porting the wastegate would apply the exhaust pressure to a larger area of the wastegate flap.

One of the basic problems with the 'OEM' Greddy is that the flap will open at high exhaust flow rates, overcoming the actuator spring, and causing major boost loss.......

Are you looking at a more robust actuator?

 

Your major boost loss is probably the engine sucking the life out of the 18G. That compressor wheel on a piston engine can make 390 BHP. Take 20% of that away and thats the approximate BHP a rotary will make with it. A rotary takes approximately 20% more air flow to generate a hp vs a piston engine. So 310 BHP give or take a few ponies. So around 240-250 RWHP is about all she wrote for the 18G on a wankle.

IF there is an issue with the actuator, it has a rod length adjustment which is good for 3-5 additional psi of spring tension. If it needs more tension, I can fabricate an actuator that will do the job.

 

Wow. Awesome.

And this will also be water cooled? Sounds like a winner for me for SURE.

 

It comes standard with a water cooled center housing and a water line kit.
