Nice work. Prtty standard. Those early engines were nice and still nice.

It would be interested to see higher rpm and a GT30R turbo.

Any vids?

kinda comes on late, don't ya think. nice numbers never the less. i'd say go bigger with the fuel and crank up the boost. that turbo can spit more power. the power cuver is awesomely flat though.

car is built for auto-x so I didnt want anything that much bigger but who knows what the future will bring. I know kinda laggy for auto-x but most of the racing is done between 4-7k. This setup is using a greddy front mount for a 99 wrx. I am happy and not that happy at the same time. I like the curve but I had hoped for the same power at lower boost levels. i think the spool might have to due with the conservative tune off boost. Who knows. And yea I would love to turn up the boost but with a stock motor IDK it scares me. We took the car higher into the rpm but didnt get any higher numbers than those scene so why take it higher than needed.

Yup a VF22 would be a better turbo choice for the power you are making. Dynapack ha?? whats a stock WRX put down on that dyno?

I wanted a rotated mount setup for future considerations.

do you have the chart with the boost and A/F ratio?

honestly that spool seems really late for a 28 ~1000rpm later than a td05

my old setup with tdo5, was about 300rpms earlier. This tune was done by a tuner that had never tuned a power-fc and was extremely conservative.. Ill see if I cant get the boost vs. A/F graph.

Hey those numbers are not that bad. I'd expect higher though, but if the car is fun to drive then great

Couple questions if you don't mind?
-Is that the .86AR?
-What size UP/DP you have (ID or OD?)
-Internal or external gate?

I'm curious as to why your car seems so laggy...I'd think that 2871 would spool faster and even a TD05 only spooling 300rpm earlier seems really laggy. Have you checked for leaks etc.?

Did you guys try pushing it more...did additional boost give you more power? I'd be curious to see any info. you can provide on the tune (AFR, Timing, MAF v's etc.) Feel free to PM me if you'd like.

Anyway, sorry to ramble on a bit. Good luck with the car and keep us posted on how it goes.

Car does seem a tad laggy but when getting into it the revs dont drop that much and your back in boost in no time. The turbo is a gt2871 with a .64ar. So basically its a gt30 intake side with a small ass exhaust side. So that could be some of the lag. I also think that the timing could be adjusted a bit in the lower revs to make up some of the lag. The up-pipe was custom made to about 2 1/4 inch and the down pipe is a 3inch. We did try some higher boost runs but I was running out of fuel and I didnt want to see my car blow the first day I had her running. We also had to go to a blow through maf setup cause we couldnt get the car to idle worth a lick with it in stock location. The setup uses and external 38mm .Illl try and stop by the shop tomorrow and get other graphs.

Cool...the more i think about it, it's actually pretty good. It looks very similiar to a 20g graph on a 2.0l. It's a tad down on power and a tad up on torque but you're only at 20psi, many of the 20g's are at 22psi or so. Spoolup seems to be the same as a 20g and the trq/hp curves look almost identical.

You are also using the small .64...i'm sure you'd gain some by using the .86.

As far as the compressor side goes, is this the 56 trim 2871? Lastly are you using the comp. cover with the 3'' inlet?

Good luck with the car I can't wait to see what you pull with 2-3psi more and a more complete tune. Should be fun to see, keep us posted
