nice numbers! thats really great man. Perhaps the load settings on the dyno weren't true to say how much you would get on the street?

[thrash]

noooice!!

[ProZac]

Excellent number. Have you got the dyno plots at all? Would be great to see. How much boost were you running?

[TOMSUN]

Plot with boost. Max was 18.5 psi



Plot with torque

[ProZac]

I bet it feels good between 3k and 4k :-).

Inspiring result... So inspiring I hassled my engine guy today to get on with the machine work for my single cam :-).

[quest]

what turbo were you running.... 16g ?
Dyno print says hp is 263.5, same as the graph shows
Dyno print says max ft-lb torque is 254, but the graph shows 354 ft-lb? which is more characteristic of a 2 valve motor(unless its really cammed up to the point it softens up the bottom end).

[1320ft]

what turbo were you running.... 16g ?

No its a Garrett something or other now

[quest]

after another look, the torque scale on the graph has to be off, seeing as hp and ft-lb of torque always equal to each other at 5252 rpm. A 16g would be making a lot more torque at the first point(3280 rpm) as well, so looks like a bigger turbo

[redzone]

Great effort Peter. Should be weelllll into the 13's now.

Turbo was a HKS 2530 but looks like it has failed after the motorkhana event.

Just dropped it off to GCG, they are going to try put a GTX2863R on to my HKS T3 0.64 turbine housing. Was going to get a GTX2860R but he talked me into getting the next size up.

Thinking I might try a stage 4 cam that I have in the shed. Might be a bit lumpy for the street?

Specs are similar to Ancor's SureCam custom grind.

I booked in for a track day at Wakefield Park 20th June, but the Starion wont be ready by then. I'm long to take my SSS pulsar daily driver instead. I have been to Wakefield before so it will give me a chance to learn the track.

I installed and dialed in the Camtech stage 4 cam last night. Had to advance the adjustable cam wheel 13 degrees to get I was concerned about a lack of oil supply to the turbo so I cranked the motor over to double check, all looks good.

Next it to install the new turbo. GCG turbos installed a Garrett GTX2863 super core into my HKS RB25 (6-bolt Skyline) 0.64 rear housing. I was really impressed with the service from GCG and they gave the rear housing a birthday and it came back looking brand new.





Next change is to swap the M&W dual coil pack and EMS ignitor and switch to direct fire LS1 coil packs. I want to do this before the next tune. So I'm not having to tune it 3 time in 3 weeks.
