Thanks to Sharif, Devon and Chris at Forged Performance for an outstanding job on my car and of course thanks to Sandy and Sharif's dad for helping with my travel arrangements. They are all very friendly, professional and do quality work. Also, thanks to GT Motorsports for a fine job on the short-block.

Okay, the project. I spoke with Sharif about building the short block for a very reliable, "bulletproof" 500whp (DynoJet). I had been running the Greddy TT @ 8psi on the stock block for a year with no problems. The previous "uncorrected" number was about 355whp. The main reason for the 500 goal was due to the limits of the 5AT transmission. We had already upgraded the valve body but also knew that, until upgraded clutch plates and a rebuilt trans is available, this would be testing the limits.

My goal all along for this car has been a balance of show and go. Here is a breakdown of the car and parts.

Greddy TT 5AT
20" Maya GR5 wheels
255/30 front and 305/25 rear Conti SP2
Do-Luck bodykit

Engine:
Arias Extreme Duty 9:1 Pistons
Pauter Billet Forged Rods
ARP Rod Bolts

HKS Metal Head Gasket
NGK One Step Colder Plugs
RC 1000cc Low Imp Injectors
Nissan Rev-Up Oil Pump
Aeromotive FPR
AAM Oil Pan Spacer
Tial 1.0 Bar Spring
AAM Downpipes w/open dumps

Cooling:
Koyo Radiator
Stillen Oil Cooler
B&M Trans Cooler
Nissan Rear Coolant Bypass
Jet Hot Coating

Electronics:
HKS F-CON V Pro

A bunch of HKS sensors

Suspension:
TEIN Flex Coilovers
(switched from TEIN CS for more stiffness)
Wheel Alignment

We also has the turbo piping chromed and the timing cover black powdercoated.

Numbers: (for now)
459whp / 450trq @ 12.5psi on Dyno Dynamics - no DJ correction.

Sharif was only able to get one good dyno run due to issues we are having with the auto transmission. We believe the issue is that the torque converter is locking up under heavy load. Not really sure until we drop the trans for a rebuilt one. There seems to be some developments forthcoming and hopefully we'll do a rebuild for more boost and power.

The car fires right up and runs very smooth. When you punch the gas @ WOT all hell breaks loose. Even with the 305s in the rear the tires are roasting in 1 and 2nd. When cruising around 40-50mph and then punch it the 5AT downshifts very quickly to 3rd and you get sideways. The power is very smooth but man those open dumps are crazy. With the exception of the trans, the car just feels perfect.

Here are a few pics and I'll let Sharif post the funky looking dyno sheet.

 

Freakin awesome. When I go FI I would seriously consider shipping my car over there. How much did this project run you if you dont mind me asking?

 

Thanks! They do excellent work. Also, they are extremely careful and clean. I've got suede and leather seats and door panels and not a mark on them. Not a scratch on the body either. They are very meticulous.

 

Sweet build. What issues were happening on the dyno? Is the VB and external fluid cooling the only things done to the 5AT? I'm a TT 5AT as well and feel your pain on the tranny limitations.

 

Nice numbers,

and on a side note that wing is sick

Rookie, according to Sharif, there is like a "pause" at around 4500rpms. It's not tranny slipping, but the rpms drop momentarily and then power comes back on and falls. We could not get a good dynojet run at all. When Sharif posts the graph you'll be able to see and I'm sure he could explain better.

 

Thanks! I'll try to get some better pics up soon. Now I just need Chris (maximumsportz) to take good vids of some runs.

 

Oh man I didnt see the wing...another SBC..Chebosto?

 

lol, I've had the same thing happen... weird. Seems to kind of stall out as far as the rpms climbing but my experience is it always powered past that weird dead spot. No torque converter change?

Do you drive in auto mode? I've found that driving in auto is pretty dangerous for the tranny. Spritied driving has always been safest for me in manumatic, I have the forged VB as well and it just doesn't downshift into the right gear fast enough as boost is building. Pretty sure controlling the downshifts in manumatic has kept my tranny alive.

Got more pictures of the motor in the bay?

 

Nice build, and nice PC timing cover, I dont know why more people dont do that when they build...congrats

 

Hi Ron, thanks for sharing. I printed off your dyno chart, and will need to scan it in a little bit later. It was a busy Friday at the shop...as usual. Sandy will kill me if I dont get to dinner...NOW.

Glad you have your baby back....looks terrific in the pics too.

 

Wow, I love the way your intercooler completely fills up and sits flush in the front air dam...

 

very nice job guys. looks like a balanced car. I hope you have big brakes or plans for them soon!

Getting a clean dyno graph from an automatic car is almost impossible with most transmissions. You have to deal with a graph of just the higher RPM. The same reasons can make it really hard to tune the low rpm and midrange also, but since Sharif tuned it im sure he had very good base maps he has made to start from that were right on anyway - and of course the FCON has closed loop self learning.

No love for the fuel system? Whats are you running?

 

No torque converter upgrade yet. I would like to rebuild the tranny and upgrade the TC at the same time. We'll see how long. I drive it pretty much the same....mainly in manumatic.

I'll definitely get some more pics up soon.

 

Thanks Alberto.

 

Thanks! Yes I have the Rotora BBK. I have the AAM return fuel system which Sharif and the guys had to make some repairs to some fittings and lines. We came close to yanking it in favor of CJM.

 

Thank you!

 

+1 How much did it run. Sharif?

 

Nice numbers for an auto. What was the problem with the AAM fuel system? And im sorry guys but those forged windshield stickers are the epitome of gayness.

 

I love it when people apologize in advance for an insult. They had to replace some lines and fittings cause they basically were falling apart. It's a good thing they got to it when they did.
