that's pretty impressive chad. with that type of spool this could make for a very effective multi purpose turbo

something us autocrossers/time trialers would like to get our hands on for sure.

 

ok, im loading some charts...... i have sooo many...

the first two are of a STOCK turbo evo IX... vs. the BBK... similar boost (the BBK was up .3 psi sorry!!) .... similar mods..

car #1: BBK, 780s, Fuel Pump, Hallman Pro Rx, BR Fmic, Dc Sports Downpipe, Cobb Catback, Intake- 83 degrees 41% humidity

car #2: Stock IX turbo, fuel pump, hallman pro rx, ams fmic, dc sports downpipe, hks catback, intake- 68 degrees 36% humidity


at the same boost levels you can see we lose about 350rpm worth of spool up.... I did not put a boost plot because I wanted to get HP/TQ curves.... I can add that later.... there is an AFR plot for both, showing that they were tuned similar, car #2 was a little leaner.

once it hits peak torque, you can see the BBK has an advantage all the way to redline... I wish we had cams in this puppy...

here is that plot..



Here is the plot against a car with an HTA3076R, BR Race FMIC, COSSIE M3's, etc... EVO IX...

you can see an obvious spool up difference... is this a good comparison? well, for what we wanted yes... because we have lots of clients that ask about HTA's, our hybrid stage 3 50 trim, and stage 4 setups..... but everyone seems to run them on pump... so that was the point of this comparison....

Had our car had a set of S1's in it, i think we would see more torque and even more high rpm power.... NOW granted, the HTA is running at 1.3 psi less boost, I still dont think running it at 25.3 would have made up the difference AT ALL in the midrange... its just way too late...

here is that graph...



ill post some more data later, when I can.... with boost plots

but this is just FYI stuff for now... im very happy with what we have come up with... our clients have been waiting for us on this... and Im happy we are at this point.

cheers

Congratulations Chad on the performance this car has made, I have enjoyed watching this thread come along....even with the wait .

With a nice set of cams I'm guessing it might hit the magic 400whp . I think you have got yourself a winner on your hands mate. These are going to go like hot cakes judging from all the interest.

Well done to all of you at CBRD.

Cheers Steve

 

Steve,

Cams will be going in soon.... caleb was going to purchase a used set, but decided not too...... so we will probably pick up a set of S1's next month...

I think it will help, but I dont think it will hit 400whp, just shy perhaps.... Kreionics car will be the one to hit 400whp on pump... he has a BR head, now putting a BR race fmic in, etc etc...

the other thing this car will get (caleb's that has the turbo we are running right now) is the JMfab exhaust manifold... If it works as I hope, Id love to pair it with our turbo in a package.

cheers,

more to come

awesome stuff!!!

 

Waiting on mine I got the Green out and am awaiting the BBK

Chad, not to cloud the thread but I will have multiple cores to send in as well.

aaron,

as soon as we are ready..... ill let you know.

im confused? you posted these numbers with the upgraded perrin intake from calebs car?

so the turbo only made 10-15 more hp over when you bolted on the perrin intake? Not looking to start something - just clarification. The tq. def. increased though......

 

I got a spare 9 turbo sitting here....want to hop off the FP bandwagon ASAP....

 

MMMM, this on e85 should be around 475whp+ no?

 

that was with the compressor upgrade alone (which had provided us with more of a power increase than we had expected).... calebs car on the stock turbo had only made around 280whp... then with the comp uprgade in the 320-330 range...then 340ish with the perrin intake (leaner because of the lessened inlet restriction)....

before.... untuned on the perrin intake, so the AFR was in the 12.0s.... and peaked upto 12.6 up top.... now the car is safely at apprx 11.7 afr and tapering to 11.2, which is more practical in pump gas terms hee he.

I am extremely happy with how it is performing.... I want to get cams in the car and see how it does..

cb

 

do you have the ability to test one on a full bolt on car running e85?

 

Very nice results Chad, you posted the data that I wanted to see. The boost plots will finish presenting the whole picture.

Looks like I might be upgrading my turbo to a stock appearing one after all!!!

 

Chad,

That JM Fab exhaust mani looks absolutely stunning, I hope this works out well with your turbo. The craftsmanship is really outstanding, they do some nice gear alright.

Is the Perrin intercooler as efficient as the BR race intercooler Chad, as it looks very good as well? Pretty late here mate, I'll check back tomorrow.

Cheers Steve

 

thanks.
