Fresh VRT dyno numbers

[_muppet_]

So I had some dissapointing numbers out of my setup last year at aptuning. Last sunday me and a few friends drove out to big three racing in the Cleveland OH area for a dyno day, and although I am still well inside the realm of chip tune numbers, I am happy to see a decent increase in power. I still have an issue, I am breaking up up top a bit, but I am 95% sure this is being caused by the driver for my coilpacks. I have had to solder it a couple times now, and need to move it away from the motor. I think I am going to get a new one and mount it to the body somewhere, as sds is very clear about not mounting it to the engine. The new numbers are on a mustang dyno, the lower aptuning numbers were on a dynojet. The only hardware that has been added between the dynos was a set of tt 288* cams. I think the car could still take quite a bit more timing, but I need to get this coil issue worked out first so I can get a good tach signal on the dyno. Everything so far has just been street tuning.

I would like to say thanks to the guys at big three. They were really cool, they let me borrow a couple tools, and are obviously very passionate about their jobs.

Sorry the video quality sucks for some reason.

sounds good! how much boost and timing?

Too much to still be at this power level. 25 psi roughly, and I taper down to 18* advance at around 19 psi, 17-19 psi I am at 19*, 13-17 I am around 20*. This is on 93 pump gas and meth, with my knock sensor on the highest sensitivity setting I don't see any knock at all at these levels.

Where is the "like" button. Nice number and awesome car.

Wow...something is definitely wrong.
I always thought the 288's were overkill for a VRT.

[PjS860ct]

288s works but it needs alot of boost

Whats the duty cycle of the 750cc?

[TBT-Syncro]

Wow...something is definitely wrong.

agreed.

You can visibly see the misfires on the aptuning sheet, I think there is still a bit of that going on, as my tach is a little jumpy up top. It definitely seems ignition related. I am looking into another complete used sds setup that I could steal the coil driver from, and I might swap the hall sender as well just for fun. Then I would have some spare parts, and could put a race gas map or maybe an e85 map in the other ecu. Duty cycle according to the sds controller is in the ballpark of 70% at peak boost, I don't think that is an issue.
