467hp/425tq @ 18psi
I think my intake manifold is the next thing I should change what is your guys opinion?
E85
9-1 compression pistons
Freshly built motor
BC 264's degree'd
My Turbo Manifold
GT32 Journal Bearing, .63 hotside, .50 comp
Megasquirt
RC1000 cc Injectors
Stock Intake Manifold
DynoCOM Hub Dyno In INERTIA mode. I have since verified with DynoCOM at SEMA that this should read equivalent to Dynojet.
At 18psi in Las Vegas was 90-100 degree F ambient when this dyno was done.

DynoCOM Hub Dyno... I want to take it over to run on the mustang dyno I have done all my other runs on to see how it compares.Kamilitaryman wrote:Nice #s holy ****! I hope I can squueze numbers like yours out of my set-up. What kind of Dyno did you guys use to tune this bad boy?
I think we and when I say we, I mean DDS (sponsor) will probably play with cams some more. I am pretty happy with it so far. What should I expect to see change with retarding the intake cam 2.5*?Kfred wrote:An intake manifold would probably help quite a bit. In the mean time try playing with the cam timing to get more top end and a flatter torque curve.
I would try retarding the intake cam 2.5* and see if you like it better.
Additionally, I am pretty sure I am leaving the efficiency range of this turbo. What do you guys think/recommend? I have been thinking that a GT30R or GT35R, I would like to try and not spool any later than I already am as I primarily drift.

If you retard the intake you will typically get more top end power and possibly sacrifice a little midrange. Every setup is different and sometimes virtually no midrange is loss but gains are still seen on the top end.
A gt30r is hardly bigger than a gt32. If you want to step up, get a 35r. Your dyno looks laggy for a gt32 sized turbo. I wouldn't be surprised if the gt35r spooled just as fast or faster.

Sorry for not replying in a timely manner. I have been finishing up second to last semester in my Masters.
I actually rod knocked two rods doing a drift exhibition out at Redline time attack a few months back. It was a 3rd gear sweeper at full lock with my modified spindles... oil didn;t make it back to the sump.... anyway the motor is fixed and now back in the car awaiting the making an intake manifold to throw on it. When I get around to the electronics I will check the timing for you guys if DDS is willing to give it to me. I know it was tuned in load with an eddy brake and the timing was increased until the power starting dropping at each rpm, then backed off a couple degrees for reliability.

nice #'s for 18psi. gotta love 9.1.1's and the degreeing of the cam produced power. alot of peeps don't do that,, they just slap me in and runs then wonder why the power gain was Minuit.
arias 8.8.1,615 tomie inj.,clevite bearings,arp 10mm hs,z32 maf,jwt ecu,intake butterflies removed,all emissions removed,cx rad. dif dual fan controller,altima dual fans,fidanza fw,stage 3 clutch,solid d shaft,j30 rearend,energy suspension bushings,kyb struts,155 lbs weight reduction.
currently n/a.
He'll probably blow the motor, and then join the army of retards who hate on KA's for no good reason.

It's crazy how much timing you can run with on E85. Crazy. Just a suggestion though... you could use some more timing in the low load areas of the map. Should help a little with off-boost response and power.

Not stock lol... had an incident where I put 3 rods through the block during a boost spike when I was at 380tq on a stock block. Oiled the track ... I don't think I am welcome there anymore.
Crower Rods, Supertech Pistons... I highly recommend both Crower rods especially were perfect and required no balancing within each other. The Supertech pistons were very well matched only about 1 gram of variance between them.

The response time is already zero. This thing is a beast. And I am fairly certain I cannot add any more timing down low safely. This car has spent a lot of time on the dyno and is tuned properly by holding the rpm constant with a varied load, adding to read the power output and then moving on to the next rpm range. When you see the power not increase or drop from adding timing you back it off a couple degrees and call it good. Then the motor will last forever and not blow itself apart when mercilessly hot lapped around the drift course of the day.adamky wrote:It's crazy how much timing you can run with on E85. Crazy.

Cool, sounds like you're got it figured out then. It's just that most timing maps look a lot like stock in the low load areas of the map, and you're running much less than stock timing in those areas. I wasn't trying to criticize. It just seemed strange to me, so I thought I'd mention it.ak_slick wrote:The response time is already zero. This thing is a beast.

Awesome power for only 18 psi. I bet that thing is scary fast on the streets.

To be honest I don't really use the low load areas... it is a pure track car... it goes into boost and stays there through the shifts until I have to wait in line.
So we ran it in on the dyno in load mode today, which is pretty much directly comparable to a Mustang Dyno (we have tested it directly on a few cars and are always within about 10hp)
I made 399hp and 390tq at 20 psi which honestly is a much more realistic number considering the turbo size. I am pretty sure I am out flowing the turbo as it always drops to the same finishing hp/tq at redline.
