Awesome , great write too
That's awesome. Never knew about a stock turbo Syclone record.Very nice work.
You have a lot of time into it .
Keep up the great work!
IIRC the stock turbo record for a Syclone is 11.94 @ 111 MPH
YouTube - Jeremy Syclone
Lots of methanol,so much methnoal,they had to lean out the fuel delivery & had to close up the spark plug gap quite a bit,(was blowing out the spark)
4L80E ,3500 stall ,lots of custom tuning w/stock ECM.up to 27 PSI,but IIRC,they ran 24 ish on the record run.
I am shooting for the 11's when I get a chance to go to a track,but w/a 20 G turbo.
I had the stock Syclone turbo record for about 5 years w/a 12.29 @ 108That's awesome. Never knew about a stock turbo Syclone record.
Yet, I did it with a stock converter
Today I worked on the turbine housing and finished up the exhaust manifold. I used a copper turbine to manifold gasket as a template and ported away.
On the right is the stock housing inlet, on the left is the ported one.
This pic shows the stock housing with the copper gasket revealing the ridge that the air sees coming out of the manifold.
Here is the ported housing, no ridge to speak of.
A shot of inside the inlet of the housing. Another thing I did was radius both sides of the wastegate hole. That should help some with air flow.
Here is a shot of the manifold flange. I used a belt sander with 50 grit to get the surface nice a flat. Hopefully I'll have no leaks.
If I recall, I didn't have to gasket match the manifolds, I just cleaned up the inside weld on it.
I didn't measure the wall thickness, but judging by my pictures, it's most likely over 1/8".
