9psi keep it up!!

I am looking to build a website for us sc'd b18b guys. Can you post your dyno charts?

Good luck!!!!!

Hey FastFour,

My static pressures with the JACKSON FMU are at 39psi!!!

Do you still have the stock Honda FPR?

That's where it's at...

Nice 311 reference...
The new album is just plain amazing

Ok guys and gals. Here is the latest poop on my POS:
On June 6th I upgraded the boost pressure on my JRSC from 6lbs (stock) to 9lbs (not stock ) The new pulley is from Endyn and known as their "stepper" pulley. The stock injectors were upgraded from the stock 240cc to Bosch 310's or 320's customized by ISA and Dr. Injector to fit in the rail.

An Apex-i VAFC (yes I know I don't have a VTEC motor, but it works just fine and as 311 would say "...fu@k the naysayers) and a Jackson Racing BTC was also added to the mix.

Now for tuning. The first pull after the new upgrades was good for a whopping 90hp Obviously the thing was drowning in fuel. After several pulls and adjusting the timing and VAFC we were able to muster 182hp and 148lb/ft.

This is only marginally better than the 168.8hp and 137.3 we were able to extract with 6lbs. The only explanation we (ISA) can come up with is the poor little blower is just working too damn hard. The M62 would probably show better gains from an additional 3lbs of boost but the puny M45 does not like it at all. It is noticieable louder though and sounds better IMO.

Now, for everday driving and my impressions of the BTC: The tuning was obviously done at WOT on the dyno. Timing was set at stock (16 degrees) and the runs were made with only 1 click (.25 degree of retard per pound of boost) with the BTC. No detonation was heard after the first pull on the dyno. Driving around town, though, induced detonation fairly often. As long as I have my foot in it and keep the revs up detonation isn't a problem. But if I'm going up a hill under heavy load (like in a gear higher than I should be) it begins to ping.

So now I've played with the VAFC settings while driving and it has helped the detonation problems. A little more of that and maybe some timing adjustment should get rid of the knock. If I can't get rid of it completely I'll go back to 6psi. I had no problems there and the car ran flawlessly and put out respectable power for the lowly B18b.

One of my biggest problem is fuel tuning. Even with several hours on the dyno since the upgrades the fuel continues to be a problem. It would be much easier to play with if I could get the static f/p down from the 56psi with the cartech. The car was just drowning up top and is leaned out up to nearly 30% in places.

But, like with any new toys tuning is key and hopefully I can tune it out, if not I'll go back to 6psi and know that I have a reliable and relatively quick car that I'm not afraid to beat the snot out of.

Thanks (as always) to ISA (Donny and Rickie) for all their time and efforts.

Zach

Fastfour, Does your car pulls harder than before? Also, are you taking your car to the track anytime soon?

I think I can tell a little difference. I'm going to the track on the 26th so I'll have time updates then.

How much did you bought the pulley for? And where did you purchase it?

[acuraboy]

Fast four, Is it necessary to buy bigger injectors when going 9psi? What's wrong with just using the stock ones.My buddy says it's better to keep everything stock as possible. Maybe That's the reason why your having all this fuel problems.

1 click on the BTC is only .1 deg/psi retard.

When I put the BTC on my car, with stock ignition timing and 6 clicks, detonation was way easier to induce than when I was at 8 degrees timing and no BTC.

Turn that puppy down a bit.

Greg,

Do you mean turn the timing down a bit? I'm a little confused. I'm not convinced the BTC is all it's cracked up to be. I ran 11 degrees of timing at 6psi and never, ever heard detonation at any time, ever. It will probably be up for sale in a bit. So 1 click is .1degree? I thought it was .25degree.

Acuraboy, I got the pulley from Endyn. I would have to say stock injectors at 9psi is an accident waiting to happen. Most here would agree.
