Another step back......... A plate I made to cover where he had a MAF mounted has popped off.
Redoing the piping with V-bands and in aluminum or SS. Getting rid of the boost braces and silicone couplers.......

At the Raleigh Convention for a car show this past weekend.
It got TONS of attention, but didn't bring anything home. Oh well. The good news is the new brace that I have on the supercharger is holding great and initial WOT runs are looking good(and STRONG).
I am getting it back for a custom 4" exhaust and body mounted torque arm next week..

Thank you!!!! Especially coming from a fellow badass thirdgen owner.
I don't have any yet. Getting things straight on it.
Hoping to run 9s with the 6 speed this fall...

Got on the dyno for a couple pulls with the new intake before I head to Clayton GA for the 1/2 event there.
My goal was just to get a safe tune to run for that and the once I get back tune for power, get a new custom 4" exhaust system, and more fuel as the A1000 is barely keeping up.
I'm very happy with the results. It made 775 hp at 6700 rpm making about 23 lbs of boost. Also, we were gaining around 25 hp per degree of timing, but stopped at 14* to keep it as safe as possible until we get the fuel issue sorted. At that level it starts doing funny things(fuel pressure decreases), so I backed down my shift points to 6500(750rwhp) and put the rev limiter at 6800. I expect to see well into the 800s once we get the last couple pieces ironed out.
With the TPI on it, the only comparable numbers I have are 555 @ 5800 on a Mustang dyno. The numbers from last night were on a dynojet. Either way conservatively, I picked up 175 from JUST the intake!

Few more upgrades!
Upgraded the fuel pump to support my new-found power.
now using a Holley 12-1800.
Also, Boostfed finally got on my exhaust and crossmember fabrication. We got a LOT done yesterday. We are doing a 3" y-pipe to a 4" exhaust dumping in front of the rear axle for now, with it going OVER the axle soon. We didn't have a mufler yesterday, so we ran 4" straight back, turned down in front of the axle. Sounds great, but is VERY loud. I will be adding a muffler and, like I said, Farlow wants to get it turned down at the back bumper. Should be awesome. All the exhaust is stainless and tigged. VERY good quality stuff here!
We also, fabbed up a crossmember mount yesterday that will soon be modified to accept the torque arm mount, so we can get it off of the transmission. I don't want to break the tailshaft when I start leaving harder....
Check this ground clearance!!!!
I'll be back in a couple weeks for the muffler, raising the rear even more and T/A mount on the body. Farlow is the man when it comes to a welder for sure!
In true Iroc fashion, I took two huge steps forward and one back. Grabbed third gear and it pulled HARD(third is now spinning
) , let off and all was well. A couple minutes later dropped her into third again and only made 5 or so lbs. REALLY weird. I am checking the usually things, like silicone couplers, etc. I have pulled the SC pulley and it turns free, no sheared keyway, sounds like it always has, the impellars are in good shape and have never touched the housing , and seems to be in great shape.
I am THINKING it is slipping on the crank and sheared the keyway on the crank, but it is strange because it runs GREAT, has a LOT of air coming out of the BOV at idle, no strange engine noises or anything just making 5-7 lbs(was over 20). Just won't make boost!

Boost leak found.......
Boost leak fixed. Now I just have to put it all back together and reinstall the SC pulley and crank bolt that I removed to try and track down my problem....

I should of noticed the flashing LAPTOP stating danger to manifold.
Got this coming to quiet it down some! Going to do 4" over the axle and single dump on the passenger side.....

Also, DeanJ has a heim joint and threaded rod we are going to use on this torque arm so we can get it on the body! I'm excited.
