A quick glance at this vehicle and one would think it was a regular stock 350z.  Under the hood of JW’s 2004 350z lies a Vortech Supercharger, Nismo R-Tune 350z Headers, and Nismo S-Tune Catback Exhaust.  To help put the power down to the ground we went with the Competition Clutch Stage 4 sprung clutch assembly with the Competition Clutch 14lb flywheel.  Once the clutch receives 500 miles for the break-in procedure, this set-up will be hitting the dyno for base numbers.  We are predicting around 350whp-375whp before tuning is performed.

Another nice set-up from Jaime from Charleston Speed & the guys at Jamison’s Custom Corvette.  540whp/502ft-lbs on this supercharged Corvette ZR1.  More info to come soon.

Layton’s RSX makes great power on a stock K20a2 engine with the Jackson Racing supercharger and AEM Methanol Injection.  The 300whp/205tq that this set-up made finally roasted the stock clutch so we upgraded to the Competition Stage 4 Sprung Clutch and lightweight flywheel.  With the addition of a better tensioner pulley this set-up is running stronger than before.

The last dyno tune that was performed on this car was back in January, which led to 300whp/205tq at a fluctuating 10-11psi on methanol injection.  The temperature were 70 degree’s and 10% humidity which yielded roughly 78 degree IAT’s.  With the addition of the clutch, lightweight flywheel, and tensioner, the engine finally held a steady boost pressure of 11.5psi and made 295whp/201tq in 102 degree weather with 42% humidity and 100-110 degree IAT’s.  We believe in ideal conditions as we had in January this set-up would be around the 315-320whp marker which is very impressive for a Jackson Racing supercharger on a stock K20a2.

Old Tune – 300whp/205tq

This car was built by Jamison’s Custom Corvette’s to replicate the 50’s era track car.  This reproduction ‘57 Corvette body is on a Jamison’s Custom Corvettes conversion tube chassis with C4 Vette front and rear suspension.   The Transmission features a Keisler 6 speed trans with stock shifter location.  A ZZ383 GM crate engine with Arizona Speed and Marine RamJet style EFI intake converted to replicate classic Rochester injection helps to make the 341whp/353ft-lbs of power.  On the Engine management end is a GM "730" type ECU.

This set-up features a built H22a shortblock (Darton sleeves, 9.0:1 Pistons, Eagle Rods), Love-Fab Mini-Me EQ Turbo Manifold, 3" DP/Exhaust, Precision Billet 6262SP, PTE 1000cc injectors, and Hondata s300 with boost control.  At 12psi this set-up is making 306whp/240tq.  At 15psi we made 328whp/245tq in 102 degree weather.  This set-up will be back soon for more boost in the quest to hit 400whp.
