awesome data.

Good thread Charlie.

 

impressive

 

Thank you very much for starting this thread this way I have more information to study.
Does Caleb have EVO IX?

I am looking forward to see this turbo matched with O2 dump.

 

Yes his a IX, I have a IX and Phenom has an VIII, i will add in the heading the year

 

on the second dynosheet when does full boost hit? I cant read the rpm at the bottom of the page..

 

I am desperately waiting what your car will put down with the turbine wheel on wednesday. Can you say 450WHP

 

im tuning a car this afternoon with the full version

yummy!

Nice.

 

Looking 4ward to some results

 

ok guys...

did a BBK car today... not one of our personal cars.. a clients car...

the car is used for roadracing, so we want a broad powerband and quick spool up, looks like we hit the nose on this one....

Mods are as follows: EVO IX

ETS 3" fmic, Weapon R intercooler piping (getting changed soon)
HKS Intake, swain coated manifold and o2 housing
S1 Cams, BR Head
Ported tbody and manifold
turboback catless
780 injectors and fuel pump

the only thing changed is the BBK... everything else was identical

it was a little cooler today, so that may have helped a couple whp... but the gains are significant enough to show regardless...

here are the graphs...

this shows the two curves.. (dashed is stock ix turbo, solid is BBK)

AFR on the right, power on the left..



here is boost on the right, power on the left...





and here is another chart, alone, just to show multiple pulls.... nice and smooth, the goal for this car..



so.. the gains are excellent..

I was going to run them at the same boost levels but didnt have time... as we got on the dyno kind of late... i suspect the numbers would be apprx 395whp/350wtq.

here are some details....we are seeing 21psi below 3500 rpm.. in 3rd on a 5 speed... pretty impressive... you also notice the turbo shows gains everywhere... its an efficient compressor wheel so at lesser boost levels its moving a good amount of air, and up top its not making the heat a stock comp would...

i think with some s2 cams, a larger fmic, and some new piping... this car would be another 425whp BBK car... not bad...

later tonight im going to post a video of how the turbos are made, i think you all will enjoy it...

ill post numbers later this week, as we have two more BBK cars on the schedule... and charlies (kreonic's) full bbk upgrade tune (currently he just has the compressor and has made 428whp).

 

amazing!!!

good info!!

I wonder how my other evo will do with that turbo.

I can't wait to see what Charlie can get out of his tomorrow.

 

Nice numbers. Solid graph for a road race car. I'm sure george is going to be more than happy.

This has probably been covered b4 (in the 60+ page thread no-doubt) but what sort of spool rpm difference is there between the Lite and Full.
