However the facts are: NO boost controller that is straight wastegate so it hits spring pressure, creeps and drops out the top. Like all E85 cars the EGTs are low because of both the nature of the fuel and the amount of timing its running. Backpressure is also generally less since the EGTs mean denser exhaust and the same volume flows through a smaller area. Probably why E85 cars dont make much power on headers compared to gas cars with less dense and hotter exhaust. The IX turbo is out of airflow and just doesnt keep up. Even on a 2.0 the powerband drops down to high 5k range when you are making 520whp (like Lucas' car when it was on the stock turbo). It was packed this weekend so Jake let everyone else go ahead of him and dyno since he can use it whenever. We are going to throw it on as soon as we can get a 34mm restrictor so we can do some rally testing as well. Aaron |
Yeah its a stock IX turbo. I just wasnt sure what you meant at first, I got it now :) A full day of exhaust from 35 cars had left me a little rummy and comprehension was low.
No worries |

No worries I would do a 35R though, not a big fan of dyno #s, like the response.. appreciate the big displacement motor & hi compression setup, good choice {thumbup} |
Isn't Jake putting on a 6262? I think that wouuld be a good mate. I think a TS 1.19A/R 4094 would be dope too!

Nah its been a T3 67mm for awhile.
|
o sorry. I that Shawn told me he was going 6262. Maybe he got his turbo confused with what Jake was doing.
Mikey |
that some good number
|
So I have sourced a 34mm restrictor thanks to Barret of AllWheelsDriven. We are planning to take the car back and throw it on the dyno and make pulls with the MBC hooked up and then do a quick retune with the restrictor to see what this combo does as a rally motor for those interested.

wow, that thing outspools the subi 2.5 by quite a lot...though the vf39(stock STi turbo) is single scroll and ve is 4g63>ej257

nice numbers
{thumbup}

Awsome power... gotta love big power out of small turbos :-)

Some quick updates (I will track down dynosheets later)-
Car made 476/495 at 27.3psi without the restrictor. With a 34mm restrictor supplied by Malcom Davies (thanks again) the car instantly lost 150whp and 6psi. First pull was 313/400 at 21psi and no map changes. 24.8psi got me 314/433 and then I realised the timing was way low because of where it was running in the map. I decided to not release the final restrictor numbers because the engine layout is going to be used in competition. Suffice it to say I didnt stop at 25psi nor did I leave the timing low {thumbup} |
Dyno sheet-
http://img.photobucket.com/albums/v5...log476-495.jpg The restrictor run drops off so bad because of the lack of timing. As soon as that got in there it picked right up :) We are going to be building a motor for Malcom in the near future that will also utilise a bespoke restrictor not using one that wasnt meant for the Evo9 turbo like we did. Doesnt help it look impressive but at least it made it "legal" aaron |
really good number man!!!
|
Sweet results!!
