Went to the dyno. 522rwhp on E85 on sS4 rotors, 67mm turbo and 950 Holley. This was 25psi, which I know is high.....but this is a low comp motor with a small street port and small RB 4bbl intake. I'm thinking about switching to 9.4 N/A rotors, half bridge and ported intake. What kind of gains could I expect. I would really like to make 600rwhp.

Is this Ira? good to see some new numbers from that little beast! honestly going half bridge is not what you need. how much timing are you locked out at? i say turn up the boost!

 

Yep, It's Ira. Timing is locked at 13*.

 

Sounds nice! Congrats.

Is your car intercooled?

 

have you stopped cracking plates? you gotta get this thing down to the new ZMAX dragway when it opens!!!!!

 

Good numbers, congrats.....

 

Do you know why you were cracking plates?

 

the car sound good.

 

Too much timing and and using S4 plates. I'm using s5 plates now. Is there anything else that causes them to break.

 

Front mount air/air(24" x 6" x 3" core)

 

Where were they breaking? I know there is a couple reasons, detonation from either too much timing or to little fuel, and ignition crossfire (leading plugs firing at the wrong time).

 

They always broke around the top dowells. I've never seen one break anywhere else.
