I recently picked up an HKS7460 Turbocharger from Sean Ivey (Iveytune) and did some testing! Huge thanks to Aaron and everyone at English Racing. Aaron's SD magic and tuning ability is uncanny. I'd like to say that I tuned this car myself, but Aaron tuned this car SOLID without even making a dyno pull. I told him the specs on the turbo and my mods and he produced from thin air a map that... without exception was SPOT on at every boost level. Aaron really can tune a car is less than 3 pulls, because he did mine without making a pull.

Big thanks to all the people who helped me to make this happen!

My comments
The torque is instantaneous. Its hard to describe, but the boost sequence is missing the lag and spool section.

before(FP Green on E85):
WOT->LAG->SPOOL->POWER
now (HKS7460)
WOT->S-POWER!

From my comparisons at the dyno this turbo is identical powerwise to the BBK, except that the HKS turbo out spools the BBK and has FAR better transient response. I should have that overlay for people tomorrow afternoon. Jeremy compared our very similar modified Evo 9's on ER SD/E85... you couldn't discern the two after 4000RPMS.

I hope to come back to the dyno with a ported exhaust manifold and a MIL.SPEC 65mm throttle body to crack 500whp

Thanks for reading. -Eric

Are you referring to Boostedwrx car on the BBK? Didn't his car break 500whp without a Magnus and a little less boost though? Regardless that looks like a stroker powerband damn near. Gonna be nuts on the road course!

You are the man Ernie. I hope you hit your 500whp goal soon!

Correct... its strikingly similar to this power curve. Granted there are some differences in the setups, but...I'll say again... VERY similar except for the spool up

Derek,

Some of this could be cams, some turbo, some weather conditions.

Eric, thank you for the review. As a friend and colleague its nice to get a pat on the back like that I will be trading you tech I am sure when I embark on phase 2 of my rally testing and rely you on as our R&D engineer on the drag car.

Too bad you are in B-ham I would love to go for a ride. I think the BB center has me going to pull the trigger on this over the BBK though...I'll have to see. That spool and I assume transient response is killer. A 4cyl that feels like a V8 all while producing almost 500whp = money!

Well hot damn! Yea Bremerton is my stomping grounds, I will make it a point to be there!

Lucas has made over 500whp with a stock 9 turbocharger. Why get a HKS turbo?

#1) Given the design of the BB CHRA it can take excessive thrust loads that a journal bearing cannot endure. Durability.

#2) the BB turbocharger kills the Evo 8, Evo 9, FP white, FP Green, BBK, you name it... KILLS in spool time. And we haven't even touched the best part.

#3) Transient response is out of this world. The time for this turbo to come to life with no turbospeed transitioning into a WOT condition is minimal at best. It REALLY makes the stock turbo and the green look bad.

#4) This was on a stock Evo 9 engine, not a built engine (if you would like to elaborate on the setup you're comparing... compression ratio, displacement, headwork, etc)

Ivey has shown what this turbo is capable of on a stock setup. You get better than stock spool and you're capable of hitting 490whp...even 480 with minimal mods and 100octane

I think its pretty obvious why the HKS turbo rocks Dave.

It would be interesting to compare to the stock turbo on Dan's beater. Curt's HTA Green too considering it ran 10.7 at 137.xx on pump gas at 30 psi this weekend. Hard to beat the HTA Green based on those results.

dbsears

iTrader: (37)

Yes it does outspool the stock IX and like said transient response is FAR better. I suppose when your banging gears at 8k for 10sec it doesn't matter. For some people having quick spool and response is a priority (ie road course...place where you actually turn and must downshift

The HTA Green most likely flows a touch more and will make all out power on kill but this turbo is directed a bit differently...Comments based on saying it hasn't ran 10's yet well it already pulled a 11.0 out in Iveys thread in a full weight car with minimal mods and this is the only the 2nd-3rd one even dynoed in the US since they came out. So Mike and David you of all people should know to give it some time to prove itself. HKS has proved itself in other venues so it will have it's place.

Its pretty obvious it flows more than a Stock VIII or IX turbo so making claims against somebody else's car is a moot point. Guarantee if somebody made "410" on a stock VIII then one would make more with the HKS given the same car. Just my 2 cents.

the graph were it out spools the 9 turbo looks like they started the pull about a 1000 rpms later ....

R/TErnie

iTrader: (32)

Brandon the first graph is the Evo IX turbo too... started almost identical times...

Don't forget you guys. The IX turbo on 92 octane was done with stock cams and stock Intake manifold. The HKS turbo was done with FP4R's and a Magnus v5 intake manifold...with a 22x12x3.5" FMIC.

So not only does the HKS turbo outspool the Stock 9 turbo... but it did it with FP4R's and a Magnus v5 as well.

Reason why the 110 octane green pull was started later was to keep the torque down. The wastegate had lots of preload and NO boost control. Thus the 110 octane... worked great at PGP. 1:10:0x's

id like to see this thing on a 2.3 or 2.4. i can spool the black up 33psi by 3850 so what would this thing do? 3000? thats crazy. its like a 16g on steroids. nice engine bay and good tune.. looks like you could run more timing uptop though with e85. i run 2 more degrees then that.

R/TErnie

iTrader: (32)

I did timing sweeps on the dyno. There was nothing left on the table. I was about 2hp per degree of timing... so very close to MBT.

I know this because I pulled 2 degrees of timing across the whole map and look to see a constant offset in torque. I also look at how much power the car loses and where. If for example I had lost 10hp by retarding the ignition timing by 2 degrees at 7k... I might agree with you. But in this case I lost 3hp. 485whp when I pulled 2 degrees across the board.

So... with all certainty... NO this car cannot use more timing up top.

By reducing power output of an engine by 1% off MBT you cut peak cylinder pressure in half.

did not see that....woops.... turbo looks like fun.... not trying to question the results just curious about them...
