HKS Supercharger owners thread

[wbradley]

A lot of people seem to think that there is no need to switch to a colder plug with these cars in the typical <300 WHP setup.
I bet the plugs you swapped were still good despite the markings. If the tips looked good that's a positive sign.

Lostpanda, didnt realize you were on the V3. So, your V3 with 110mm pulley produces almost the same power as my V1 that also has a deleted restrictor plus a larger intercooler. For stock fuelling I am so maxed out that the tuner felt it best to set fuel cutoff to 7100 RPMs.

I decided to leave my tune at that point even though I already have the injectors, only need a fuel pump. Reason, I dont feel the need to spend thousands more for clutch, drivetrain upgrades etc and I am CERTAINLY not willing to blow an engine. Frankly, I dont think these cars are my idea of a drag racer.

90MM with the big injecters is the good way.
But the pressure will be 1.1 bar on this V3 7400RPM so I must change so many staff for my engine if not, I think it will very dangerous.

With the stock fuel system, around 1 bar (14.5 psi) could be supported like below. With 100mm pulley + 7800 RPM, 100-200 km/h cleared in 10 seconds.

If you have moved fuel cutoff to 7800 on stock fuelling without leaning out I am shocked...that you havent blown a hole through your engine!

AFR is well maintained between 12:1 - 11:1 until top end.
Injectors still have margins but not much.

Stock injectors and stock fuel pump?

[scmil95eg]

A completely stock unmodified engine will do that to a stock plug. There isn't anything there you need to be concerned about.

What do the straps look like?
What does the porcelain around the electrode look like?
What does the fuel ring look like?

Torry ?
Any news about the table ?

Sorry, been busy and forgot I said I'd put this together. I'll be out of town this week attending PRI, but I'll try to work on this next week. Feel free to remind me again if you don't see it in a couple weeks.

Can our FA20 bear the 1 BAR from the supercharger ?

My tuner told 0.8 is safty.

yes. stock engine can handle 1 Bar boost easily.
I run 14psi over 4months with HKS v2 S/C.
but without Methanol or lowering CR, it does not make more power than .7bar of boost.

Ok, made this:

Anything else you guys think should be on there that I'm missing? I forget what all parts everyone was asking about.

Where is the traction fluid filter found on an installed system? (V2)
