T3 on a 12A??
I've got a shot at a cheap T3 off a 89 Thunderbird... Is it big enough for a carbed 12A turbo project with 7-8 lbs of boost? or am I just going to run outta top end?
|
I was told that even my bigger turbo(non-stock) off of my Grand National wasnt going to be sized correctly for a rotory, so I'd imagine that tiny litte thing wont be worth it...

Not in the least. Start with an HT-18 from a Turbo II RX-7 and work up from there
|
The HT-18 is a good turbo, it would be an upgrade over most turbos from other cars. From what I have heard, basically the hot side is a T4 and the compressor is a T3. Its good for about 250hp on a TII, so I think about that is easily atainable on a 12A, which is enough to give you major traction problems with anything less than a high performance tire, good for a mid 13 quarter mile I think.

Not to mention you can hybrid the HT-18 with a T04x compressor side to run more power efficiently and relatively inexpensively

I'm going with just a stock S4 HT-18 on my 6 port for now. Should be good to get me the power I want I think. I MAY go with the hybrid style that firebirdslayer mentioned. Depends on time and money. I just wanna have it running for the spring at this point.

But, he is talking about using a NON-rotary turbo - I saw in a big thread about turbos that the compressor/turbine sizings are basically opposite from most piston engine set-ups.

MOST Non Rotary turbo's don't flow nearly enough CFM for the rotary motor. HT-18's are cheap, easy to find, and are perfect for a 12A Turbo build
|
I understand. He asked if it was big enough and I responded in my first reply "Not in the least". It wont flow enough for a rotary as most piston engine turbo's will not. My route is going to be a hybrid from Robert at Rotary Shack. Maybe I can send him enough cheese as payment LOL

thats why most guys look for a "P" trim wheel in about a .84~.96 a/r when they upgrade For a piston engine a .84~96 hotside with a "P" trim wheel is in the 6~700 flywheel hp range, but for a rotary its only about the 450~500 depending upon compressor wheel. kenn |
The 12AT came with a T3 turbo.....

K. I'll go with something bigger, if it ever comes along. thanks guys!
