Dyno 348 horse/279 torque @ 14 psi on Rtek 2.1
 

Went to a dyno day on Saturday and with the new injectors and different turbo I wanted to see what it would do @14psi. The first run was at 10psi then the rest was at 13-14psi. There is probably more in the setup, but I'm just using a map that I made from using other peoples base maps and from reading around the forum. The AFR's where around the mid 11's. I still have to get around to leaning it out some around 4700 rpm and richening it up a few points at around 5400 rpm

how is the RTEK 2.1 work for you? im kinda curious about it

really nice. is this on a stock port?

Looks good.

I'm impressed that you made that kind of power with the stock AFM. Did you use the new MAP based timing feature?

I like the 2.1. Its farely easy to tune and having a way to log some runs is awesome.


Stock ports


Yes i'm using the MAP based timing.

how many degrees of advance at peak boost and at what split? Did you have a flat advance curve or gradually increase timing near high rpm, past torque peak?

wow i am really impressed that you made those numbers on a stock port at only 14 PSI. I will be tunning within the next couple months on a pretty much identical setup so now i can hopefully expect something along the lines of this.

My timing is flat above peak torque. I might try to raise it a degree or two though, but I don't know how much of a difference it will make.

13 degrees split is on the conservative side. Most run 8-12. Looks pretty good though.

Is that 92% injector duty-cycle number accurate? What FPR and pump are you running? Either way, nice numbers and nice ride!

Looks pretty good your diagram.

Perhaps you should try, 1 or 2 degrees up, after peek torque and yes, a few degrees less split .

Very nice .

From what I can tell its accurate. I'm running a Walbro with a Aeromotive FPR. I'm happy with it right now and if I want more then I'm going to have to figure something out with the injectors. I ride around with just 10-11 psi anyways and its more than fast enough to have fun with. :)


Maybe even adding some kind of meth/water injection could be in the future.

nice what turbo are you runnin?

sweet, looks nice man. I finally got to drive my FC with your old turbo and it's awesome. Keep up the good work man.

..... Masterpower T60 .96 A/R

impressive...

Nice

stock ports?

Yes on stock ports.


I'm not running the Masterpower turbo anymore. Went to a Turbonetics 60-1.

any difference?

I don't see to much of a difference. Maybe a little more torque. I went to the Turbonetics because the oil seal went on the Masterpower turbo and it couldn't be rebuilt for some reason.


Here is the chart with the Turbonetics 60-1 with a .81 rear housing.

nice numbers. almost same setup i am using except i got a turbonetics 62-1, .81 a/r also.
last dyno session i clocked 348 @11psi before some engine gremlins reared their ugly face. but mine is street ported and 850/1600 injectors. looking to go back soon and strat turning up the boost on mine!! 400+ on pump is my goal and +/- 525 on race mix.
but on stock ports, those are nice numbers!! congrats.

from what ive read... .81 rear housing is too small.

too small for what? depends on what you are using the car for... .81 rear housing is commonly recommended for a good spooling street turbo...
