ZZP Did What?
 

A couple weeks ago, Zoom instructed us to test the ZZP LSJ rods and/or block girdle to failure. Ryan and I thought this would be an easy task, but we were wrong...

i saw the post on facebook but no REAL numbers were posted ..

1000-1500whp?.
Aluminum or steel?

interesting

I soooooooooo want your job! Lol

in for results as well

clicky

zzp owns ALL

Well I guess Matt couldn’t have said it better because that’s exactly what I was thinking as we were doing this testing. I figured a big turbo and a lot of boost would make it easy to destroy an engine but I was wrong!

I ended last season with the car trapping 138 at about 30psi. Unfortunately the unsupported sleeve on #4 cylinder let go as I was going through the trap. We dissected the motor and discovered that around the ends of cylinders 1&4 there is absolutely no cylinder wall support. Well we need to fix this and what does the crew at ZZP do best, come up with solutions to problems when others can’t! This lead our team into building a cylinder/block girdle for the motor. Well, does it work; I guess I will let you be the judge of that.

Current mods on the car:
ZZP forged engine with block girdle and balance shaft delete (LSJ block with stock sleeves)
ZZP ported head and stg. II cams, adj. cam gears
Supertech Valvesprings
ZZP LSJ Turbo Kit:
-ZZP cast turbo manifold
-LK9 intake manifold
-2.4 throttle body
-Precision 46mm waste gate with 25.5psi of gate spring
-LSJ turbo swap intercooler piping, 2.5”
-Manual boost controller
-Optional ZZP Race IC
-Optional Bullseye Power Billet S366 w/ race cover. T3 .70 A/R exhaust housing
-Optional 3.5” down-pipe
-Optional 4” turbo intake
-Optional 2000cc injectors
Dual in-tank pumps with a magna fuel pump in series all fed through factory feed line. (Magnafuel pump for dyno testing)
Fuel lab regulator returning fuel through evap line
ZZP electric water pump and thermostat housing delete

I'm heading out of town. Matt is going to post more info today.

Did you guys get a dyno for the 138mph traps?

Ryan's highest dyno last year was 624whp std. I think it trapped 138 at a couple psi less boost, though. Maybe 590-600whp.

Wow.... just wow....lol

Ryan got his car out of storage about a week ago, and he went to work. He installed the new ZZP 2.0 LSJ engine with ZZP rods, pistons, and girdle. Then he installed an off-the-shelf ZZP turbo kit with the exception of the following: He left his race intercooler on from last year. He installed the same S362 turbo he had from last year. These parts are available by request as part of our LSJ turbo kit. Ryan also put together a custom canister with dual LSJ fuel pumps and we ran an 8 gauge wire from the fuse panel to the pumps.

We got the car on the dyno on Wednesday. We started with the S362 turbo on 110 octane. Starting out conservative and working our way up, the 9th pull was 545whp at 23.5psi. We kept moving forward and the 13th pull was 604whp at 29.4psi and a conservative 11.2:1 afr.

Next, Ryan drained the break-in oil and switched to a synthetic race oil. We also pumped out the gas and switched to our amazing 90% ethanol blend. The next pull was 396whp at 16.5psi. Pull 20 overall was 637whp at 30psi.

yum

Alright (was curious for something outside the thread)

Good numbers, too bad there aren't many more like it.

lets see some numbers in the 700's next =P lol. keep up the testing!! =D

I got me an email lol. If I see the dyno numbers right all I can say is WOW.

Next, we switched to a Bullseye Power S366 turbo with billet wheel. Turning up the boost, we ran into ignition issues, so we regapped the plugs to .026”. Pull 23 was the last pull on the full ZZP catback at 643whp.

Next,we switched to open an open downpipe. Turning up the boost, the turbo hit hard enough to spin the tires to 158mph on the hit!

Next, we switched to slicks and tightened the straps tighter. The next pull was 690whp.

Pull 29 overall was 719whp at 35psi. I left after this pull, but Ryan was still planning to turn it up a little higher. Dave, from Bullseye Power was at the shop to test with us. Pull 33 was the last of the night with 751whp at 40psi starting to break up again.

Nuts, Where does he park this thing again, need an address.

My other thing is what tranny?
