HKS Supercharger from Evasive Motorsports
 

I got my HKS Supercharger installed and tuned last week at Evasive Motorsports in Santa Fe Springs (as well as installation of a bunch of other stuff). Randy over there was incredibly helpful the whole time. I got the basic HKS kit, fuel pump, 700cc injectors, and Perrin oil cooler. It still has the stock exhaust with a cat back so that's holding back the numbers a lot as well as only a 9psi pulley (opted for going with less psi for longevity of the motor). The tune is fantastic, really smooth pull even from the low end, and is a fantastic daily driver. The idle needs a bit of work but that's my fault cause I had to take the car back before they could finish doing all the tuning.

The current dyno is at 216whp/180tq (stock was 156/128) with the restrictive exhaust. Hoping to be above 230 when I figure out how to make it quiet enough to drive around California. I couldn't be happier with Evasive Motorsports or their customer service.

Some pics of the setup:

Ouch...

rotas and an HKS kit don't go well together :) never the less great build !

38.5% deltaHP and 40.6% deltaTQ increase. Where's the ouch?

Looks good to me, although I do wish those Rotas were TE37s. Did you get any dyno plots or boost plots to post up?

:sigh:

HKS SC looks like a plumbing nightmare, but I'm sure it runs really well.

I do but I don't have it here at the moment. I'll post it when I can. And I wish the rotas were TE37s as well but the rotas were a good compromise.

Congrats on the boost!
:burnrubber:

Sucks about the California laws, headers are such an easy switch I did it in an afternoon. (I am just learning to turn a wrench)

Based on the stock car 156whp/200hp, your dyno number is 216 whp which equivalent to 277hp; So this is way on bar w/ stock S2k or better. A little more fine tuning you can get several more HP. Man, this is damn good for DD. Can't ask for more :)

I'm jealous

Be broke for a long time.

Once I figure out the exhaust and get some final tuning I should be into the 300s. It's definitely a good amount of power for a DD which is what this car will always be.

Start with a un catted header, then a high flow cat (secondary ) maybe keep the stock catback or go for something quite like the q300 !

we just installed a q300 + CATLESS front pipe and its super quite !...well compared to my straight pipe :scared0016:

Stock S2K is 240hp at the crank, don't know what they usually dyno at though. They do have a gearing advantage as well.

Congrats man - I think I saw your car there when I was getting my big brake kit put on! If you see any drool on your supercharger, it might've been me hehe ;) (j/k of course)

i know a guy with a avo turbo fr-s who walked away from a s2k. just saying.

As he fucking should, it's a goddamn turbo!

i know a guy with a full blown brz who walked away from a sti. just saying.

I know a guy with a full blown innovative greddy vortech P&L kit that walked away from a 7-11.... with a cherry slurpee. Just saying.

Penta charged with a slurpee. Was it the most interesting man in the world?

Nah, Chuck Norris. He was walking because it was faster than his pentacharged FRS.

Glad everything worked out great Josh! Little more tweaks we can sure more power can't wait to see this monster again! Ill send the Dyno Graphs tomorrow to your email.

Ok here's the dyno sheet. Sorry for the quality (I have no scanner here)

Randy: Thanks again! I'll hopefully be back in the next week or two.

Interesting to see that dip at 6400. It shows up on a number of FI dyno charts.

I'm sorry I didn't reread the entire post, are you running the stock fuel pump/port injectors? Also what boost? Our dyno polts look similar. I'm going to be replacing the fuel pump and port injectors to reduce the load on the DI's up top.

I looked it up and aftermarket fuel pump with 700c injectors, @9psi and still with the 6600 dip :( sux.

The dip I believe is almost entirely related to the exhaust (I could be wrong, probably am) so when I get the exhaust and the retune done I'll post the new dyno sheet.

Yeah back pressure... Prob

AP1's with the F20 dyno between 190-200whp. AP2's with the F22 are between 205-210+.

It looks good man. Hope your liking this kit.

nice numbers! quick question here, i assume Evasive tuned it w/ Ecutek? do you still need HKS' Fcon computer installed along w/ the kit for the tune? I thought the kit comes w/ the Fcon, if so, what did you do w/ it? i might pick up the same kit locally to save on shipping.. do you know if Evasive do e-tuning? thanks!

Interesting... I just saw you in HB. Mentioned in the SoCal spotted thread.

Vortech SC Kit...
http://www.moto-east.com/dynos/ft86/..._brz_263hp.png

Hmmm... Both incidents are at 6500 RPM. I'll be checking out another Perrin tuned Vortech kit plus doing a HKS SC tune soon as well. I wonder what that issue is...

What's also interesting there is that one SC smooths out the torque mess at the lower rpms and the other does not but, as you observed, they both have the same problem up high.

I think that is a function of the headers more than the sc, I still had a little dip before I put the borla header in.

@Drift-Office @Pete

I have a pump/port injector upgrade coming on Monday then @moto-mike will be doing another tune on my car, I'm hoping that the upgrade will take care of the dip at 6600, otherwise I'm thinking maybe it's the borla collector fucking me

Which it could be because the stock collector is almost as bad as the borla collector.

The torque mess as you described is proportional to the amount of boost running (one's @ 7 and the other is at 9 if memory serves) with the latter other one running a Borla UEL? Without a boost log, I can't be sure but it's a good bet looking at the 2 graphs...

I didn't have that dip on the Borla UEL after I tuned it out ... and the latter OP said he has one in his car...

So it's an anomaly that's not SC related, not brand related, not fuel related (the latter had 700cc injectors?) and not necessarily boost related... I know I've run higher boost in that 6000+ RPM area and I've never seen that before... Weird.

Are both these cars AUTOMATIC?

My car the moto-east tuned vortech had borla and stock fuel pump/injectors I'm the dyno with the 263 max HP on the dyno jet, the stock baseline was not my car, it was the highest stock car moto dyno'd.

On Monday I'll be changing my pump/injectors to 290, 500 port injectors. Hope that clears up the confusion, my car is also MT.

I don't believe it's using the Fcon anymore and that it could be in my parts box that I still need to pick up but I'm unsure. If you contact Evasive they'll tell you everything you need to know.

I still had a small torque dip around 3500 RPM after I put in the S/C, but later when I installed the borla UEL the lower rpm dip went away entirely.

This is my dyno with the old blower (stock header) in blue vs. the new blower (after borla UEL) in green.

What is interesting about adeets' dyno is that he has a dip at 6500, but then the torque shoots back up afterwards. In my dyno my torque begins to decline at 6500, but I don't have the surge back up afterwards. If Moto-east has found a way to maintain torque levels all the way to redline that is great news for all supercharger owners. I'll be watching to see what he can do with it in the future.

:w00t:

Who's doing your FP install? Its very tricky.
