HKPRO5's Supercharger Build Thread

hitting fuel cut. The maf is getting to much pressure and flashing. tried used a voltage clamp and nothing

ANYONE HAVE IDEAS
 
Yea make sure that it's open at idle.

Any chance to get your hands on some 440 injectors?
This seemed to help the previous owners MAF problem.
 
so right now im running a psc1-020.

as we cross into boost we hit a wall no matter how much fuel we dump we still get fuel cut off.
 
Its true AUTOs loose alot of power. I dynoed at 73 whp. soo roughly 88hp.

Finally went and tried to dyno and tune the car. I have pretty much the same kit as HKPRO5. Started at 220 injectors (stock) and maxed out and hit fuel cutoff at 2psi. Moved up to 330s that came with the kit and Hit fuel cut. I didnt have anything else soo could do real dyno run. Im going to get some 550s this way i can hit my 4psi and then some if i decide to upgrade the pulley.

What i say below is from my experience today.

Couple things for those that are going to go the supercharger route. 1) Wrap your headers 2) figure out some way to to heat resistant the intake on the supercharger. IT GETS SUPER HOT SUPER FAST especially being soo close to the header 3) If your going to run bigger than stock injectors id highly highly recommend a 255 fuel pump. These are my next step before actually getting a proper dyno number.

BIG THANKYOU TO HKPRO5 for helping me out today. 440s was the way to go.

Ceramic coat this as well, then make an aluminum heat shield.

No problem, I told you the 440s were they way to go the first time around.. lol I have a site for you to pick up the other injectors, I have to take a look though. If anything the STI pinks are 565s. and are a direct swap.
 
thats weird that your hitting fuel cut so easy....and in all honesty, you dont need to upgrade the pump. I was running 14psi on a GT25 setup, with stock injectors and stock fuel pump. I JUST NOW upgraded to a Deatschwerks 300lph pump, now that im running 440's and a bigger turbo. I doubt that I actually needed it, but I did it just in case
 
^ the previous owner of my kit needed 440s in order to get around the fuel cut and MAF issues just like Flip. Not sure why, but going with the bigger injectors helped. (although i didnt have a problem)

K well as i mentioned. With the experience i had yesterday.....It would be a good idea.
How about its a worth while investment. Better safe than sorry.

Ya it was weird. We tried the O2 clamp, we tried moving the MAF we tried a couple different things and after a call to sunny Hawaii. Problem was fixed with bigger injectors. Soo as mentioned Im going to go straight to High Impedence 550cc injectors. (really like those pink 565cc injectors too)

Overheating issues was a big concern. The intercooler setup worked great but because of the placement of the supercharger. Im going to be wrapping the head and wrapping the intake of the supercharger.

Overall im stoked to get the bigger injectors and head back to the dyno. (really considering the manual swap now) 73whp!!!!!!!! wtf
 
you should pick up some thermal reflective tape, get some stuff ceramic coated, and use the wrap where needed. lol

Also i think the reason you guys had problems when using the o2 clamp was because you didnt pair it with the Rising Rate Fuel Pressure Regulator... (which i told him that usually those are used together)
 
Everything in the engine is powdercoated except the supercharger. Im about to order some reflective tap and header wrap online. I might be sending out the CAD design to the other pulley out this week as well. Might just straight up go for the bigger pulley and tune that up
