Supercharged KA build

[ss82480]

Ok here is the scoop. The car was running LEAN as hell when I first got it to the dyno, close to 17:1 af ratios at WOT. It first dynod 166whp, then they added +20% fuel across the board with the safc and hit 198whp. They tried upping it more but the numbers went back down. About this time I realized that I originally planned on low boost, which meant I was ok running stock fuel pump. Since on a whim I decided to up the boost, I absolutely overlooked my fuel pump needing an upgrade.

Needless to say after a little leaning out on the new fuel pump with the safc the first solid run was about 211whp with 200wtq. The following dynos the a/f ratio was tweaked but the peak power remained about the same, due to heatsoak. I got video and dyno charts that I should be able to get up by tomorrow.

200+ whp and tq?sounds like a fun *** car !any other planned power adders?

[ss82480]

At this point I am just going to add things to keep it running good. Down the road I might consider meth injection, a bigger throttle body, or getting the cams degreed in.

This is beastly! I just heard about this thread. I can't wait to see this car!It's good to know DFW's local 240 scene is becoming so diverse!

[zismo02]

Nice setup!!!!!!!

I haven't seen any SC KA's or 240's matter of fact.

But, you should def hop on a EMS.Because my boy had a SOHC KA-T with a T3 super 60. He put down @ 7psi 210 /235Ft-bs.

I know they're totally different, but I think you could make more power with you setup.

im not worthy ....

thanx man it looks awesome!!!

[ss82480]

Thanks for the comments guys, it definitely took more work per horsepower than a turbo kit, but I think it was worth it just to try something different. I think I might be getting spark blowout a bit too, which could have hurt my dyno a bit but I'll have to change my plugs out and see what results I get.

[WDRacing]

Just decrease the gap a little. I start at .035 and work my way down until I don't get blowout. Although I don't think you should have any blowout at your boost level. Never decrease it shorter then .028 IMO. If at that point you are still having issues, you need a better coil or more voltage.

kick'n build... I got to get a ride in it this weekend

[XMSducksauce]

ok so i tried to make a drawing of what i was saying

This picture = win

[LovesBigTurbos]

sick build looks sick hahha never enough power!!!

[ss82480]

Sorry it took so long to get these up, but here is the dyno for it. Criticism welcome, I am still looking to squeeze out a few more hps, but consider this is with quite a bit of heatsoak at 85 degrees ambient.

[LovesBigTurbos]

nice pretty solid numbers

[Darchangl]

I get to whore out his videos!! (my fault why it took so long to post them, sorry )http://www.youtube.com/watch?v=PpXWkSx2 ... N3c_BkQ89M

[Jay97240Sx]

Sweet dude, really sweet. Love the supercharger whine

[AJxr]

how much boost where you running when dynoed? safc tuned like as stated?

car and setup are clean!

[WDRacing]

I think you should toss the stock cams in and dyno it again for a comparison.

[240cp]

Man i didnt realize how much i missed that sound till now . Nice vids sounds great. Pretty nice number for low boost. I agree with wd, put back in the stock cams, i bet boost goes up and maybe power

[ss82480]

I will keep that in mind about changing the cams, it has already crossed my mind since I hear mixed reviews on the BC cams. It was at 9psi on the dyno, and yes was fine tuned with a safcII.

[BoostFab]

nice to actually see it in person last night; when I was at the track with Aaron.

a friend of mine said the BC cams are copies of someone's else, and they have becoming less consistent, but that's just rumors.

[sil_eighty86]

Just picked up the same kit for $700 with supercharger. I will start my own thread but I wanted to say thanks for the inspiration.

[gingerbredman]

AH loved the vids! Awesome man, hey where did you have those BC cams dialed in on the sprockets? stock positions or otherwise?

Yeah, I'm thinking with a supercharger setup, stock cams would probably be more efficient, without port work and such. Since the supercharger's powerband is broader than that of a typical turbo'd ka.

Sounds awesome, can we get some vids of it on the street, or track???

[a_ahmed]

I was gona say we need street/highway/track videos now!!!

[turbonola]

now we gotta get someone to whipplecharge a 240

[airman86]

or kenne bell

[HOMEMADE240SXTURBO]

can you please post a link or website to every or most part you bought to put the kit together? it will really helps us in the future.

[ss82480]

I bought the adapter plates from Thomas Knight and the s/c from ebay. Theres alot of custom fabbed stuff as well.

The best I could get at the track is a 9.1 in the 1/8th, was hoping for better. Maybe I should get serious about tuning the cams and maybe some kind of cooling. It heatsoaks so much that my times get slower as the day goes on.

[Shift_Kouki]

What about switching to a different fuel like E85 for cooler burn / charge cooling?

[sorrowfulkiller]

What about switching to a different fuel like E85 for cooler burn / charge cooling?

E85 + Water Methanol Injection = Teh Win

OP you should save up for a whipple twinscrew once you get this thing dialed in... that would be sick as hell!

[ss82480]

Been running strong for 8 months, an updated picture of the setup.
