Thread: Dyno predictions - Thursday night

Thanks guys. I definitely left with a smile on my face. I made a mistake, the test pipe was on (no cat), but my 3" exhaust narrows down to a crappy 2.25" muffler. I will be putting the 3" magnaflow muffler I have in the garage back on. I imagine I will still pick up some power as it was a restriction.

As far as the water/meth, only running windshield washer fluid that has about 38% meth in it. I am going to buy Snow Performance Boost Juice, which is a near 50/50 mix.

I am running the .84ar turbine size. I am injecting about 12-14" from the TB. I would need to look up the injector size, but it was the 300hp recommended size. I will ask them if I should up the size. Intake mani stayed nice and cool, even after 9 dyno runs.

The big hiccup of the night was the JWT ECU. Ultimately, it performed great. However, I was told it was a 3bar program. Turns out, it was a 4bar program. Got the fuel pressure dialed in, and it was good to go. Rock solid A/F. Very impressed.

Here is the graph. I overlayed A/F and Boost on it as well. Came in and put down 220 on 8psi. Left with 100whp more

2.25" is a MAJOR restriction.... you don't know what size injectors you are running? thats pretty scary. if they are the "300hp" injectors, they are probably 370cc at 4 bar fp, which means you are maxing them out

EDIT: your sig says 555cc injectors, that makes more sense

When I said that I was referring to the size of the water injection nozzle Sorry about that lol.

Nice what was the boost at when you left?

fix the muffler and use a 50/50 mix then you can mess with the timing. I bet there is another 30-35whp to be gained. If you plan on keeping this setup I would go external gate. it really helps out small turbos.

Changing the muffler out today. Also ordered a four gallon Boost Juice pack last night before bed. I would definitely consider going EWG in the future. I will hit the dyno again in the next week or two with the small changes.

I left with the car boosting 19/16, as in the graph above.

One problem fixed. The dual tip muffler was 2.5", so not as bad as I thought. However, the entire rest of the system is mandrel bent 3", so there is still some power to be gained. It feels smoother already, and quieter.

sexy

Dont forget to rotate your tires. And fix your freakin lights, lol.

So when is the next pull?
