Boost drop was more significant when I installed the stage 2 turbo cams the same time the b207r went in. It had a blast of power up to about 5200 and then fell off instead of tapered off. Car felt way better on the stock LSJcams+k04 before the motor overhaul. The stage 2 cams really came to life...

Which turbo did you go to ? How much boost are you allowing ?

The Goblin can easily take a TTOD spot, last PCA event I went to It was 4 seconds faster than anything else that showed up that day. But the Thscc guys are faster than the PCA guys Your tires are killing you. If you can run stickeis call up JB racing tires and get a set of used takeoffs or buy...

I also run 15's and ended up replacing the front shocks with the 1 inch longer shocks up front and opted for double adjustables. It gave me more room to adjust the ride hight up on the coiliver and a bonus was the added droop provided more front end grip coming out of corners. I shortened my...

Looks promising ! Now if you could just figure out how to get an UCA in there this kit will be on par with the Atom.

Maybe pull the valve cover check your timing chain and valvesprings.

The base pressure is set at 43.5 PSI with the reference line disconnected. Duty cycle is around 56.2 at 22psi and 6200rpm. There is still plenty of fuel that can be added but I'm not thrilled about how jagged the AFR lines look. Attached is a log of it running lean.

The AFR's are going lean while Inj Duty cycle is following the Maf curve. I'm not sure how much the pressure should change at the rail but I guess if the reference is 20psi shouldn't the rail pressure also go up 20 psi ?

Updated the fuel to a Boost reference system. Mounted an 8 gal fuel cell where the passenger seat would be to balance weight left to right. Feeding an inline pump from the bottom sump then to the fuel filter. From there the return is intercepted by the boost reference system which keeps the fuel...

I believe the tank may be a bit wider at the bottom than the top. I recall the angle of the firewall side following that angle getting wider at the bottom.

The b207r that i used to replace my Lsj had the sensor on the block just above the starter behind the oil filter. You may be able use that spot instead.

That is a nice setup should be well balanced. Those tires heat up very fast so if you decide to do an autocross bring a tire sprayer.

In case anyone missed it Andy Hollis did a good scientific 200 treadwear tire test and tested the "top dog" track and autocross tires in their respective settings. Since then the RT660 is a new contender but it is mostly used in the spec class and does not heat up as fast as the yokohama a052...

When picking wheels it is very important to figure out what your backspace is. Backspace is the distance you have from your hubface or the surface that your rim will attach to on the brake rotor hat back to where your rim will contact suspension or body components. You can measure this by using...

They are awful in the rain, follow all the ruts in the road, throw rocks everywhere, heat cycle out quickly and love to pick up sharp pieces of metal. It is really really really difficult to put a plug in them also. I feel like I get about 6-7 good heat cycles/events out of them then they slow...

I have run a lot of sets of the A series Hoosiers for autocross. I would not run those on the street ever. An autocross should serve well for an initial scrub in then you can let them sit until the next autocross. Like Dale said you will have to deal with OPR on the tires which can make you skip...

Where did you end up with your pressures ? Are you running just a rear swaybar ? Is the Goblin working better with it disconnected ? I wish we had more practice autocross here feel like when we make a change we have to drive a different course and have no concrete results.

Best thing is to watch a few videos on EBC's to get an understanding of what they do GFB Gforce III Electronic Boost Controller Overview - Bing video Amazon.com: Go Fast Bits G-FORCE III Electronic Boost Controller Turbo EBC w/Air Fuel Ratio : Automotive if your set on a manual boost...

I wouldn't waste my money on a manual boost controller with that turbo. I got the GFAB3 electronic boost controller and couldn't be happier. The manual boost controller will set a target boost then open your wastegate. An electronic boost controller can set a target boost, help boost come in...

Went ahead and ordered the Zzp brfps . Looks like its a pretty simple solution that uses intake manifold vacuum to lower pressure to help alleviate big injector idle issues and raise pressure during boost. Hopefully this will help keep my maf cells populated with VCM scanner more stable. It...
