DYNO DAY JUNE 26th

[whatsisname]

25psi! This isn't on stock internals is it? I'm guessing no. 25psi of supercharged boost + 5.7L ='s serious grunt! Can't wait to see it in action Martin.

[Martin Donnon]

Yeah Matt, I have to use C5R Lemans bits in the engine to make it hang together!

[skidmark]

can we go backwards on the dyno day pleaze i have my spark problem fixed now and want to have a go i had it on the boost worx dyno yesterday

and puled a whole 88rwkws who hoooooo due to a :flamed: burnt plug

Mmmm C5R Lemans :drooling: So what's the ETA on the new package?

[9krpm]

^ what's the expected power as well Martin?

[Martin Donnon]

Would like to see it at the track within two months

Power output? What it makes, but it should be close to 700rwkw

is it going to be street legal though ? :sly:

[whatsisname]

Holy shite! With a possible 700rwkw (we're talking within kickin' distance of the big 1000rwhp!) who cares if it's legal or not? I just wanna see it get up and boogy Awesome stuff Martin, bloody awesome!

[Martin Donnon]

Well to give you an idea Matt, we finished off a Crewman today, with some pistons, rods, small valve heads, and a rather big cam 240+ duration, running 11psi through a T Trim, on a stock 5.7l capacity, and it made 496rwkw at 6400rpm. Now factor in over double the boost (from a bigger YSi compressor), more displacement (C5R on an iron block makes 6.0l), decent fuel, much better manifold/heads, twin 4 inch exhaust etc. and you can see where I am angling from. 700rwkw isnt guaranteed, but its quite likely to be on the cards. The best part is that with the crank/rod combo I am running 8500rpm is the hardware ceiling.

Going to run reprogrammed factory management too. Give the old keyboard skills a workout it will!

About as street legal as most other cars on here you might say :sly:

[whatsisname]

6.0L, 25psi, 8500rpm, jungle juice fuel and enough air in and out to keep a diver on the ocean floor for a decade! That's worth a Big Kev - I'M EXCITED! I'm guessing Damo (Rogue8) is clued in on Tonners progress, yes? I'd love to be there when the tuning takes place.

So what sort of chassis upgrades are in the works? The torque this thing will develop would snap the stock chassis in half wouldn't it?

I have to say, I'm bloody amazed at the tuning scope of an 'edited' ECU. GM have dropped the ball in a few areas, but the ECU certainly wasn't one of them.

Street legal - my car is 100% street legal, dead stock, never had so myuch as a Gtech fitted to it

[Martin Donnon]

You would have to argue how far they really have dropped the ball Matt. One of our latest discussions over on the dark side revolves around a stock unopened engine manual VU ute (exhaust, filter, tune etc) that just ran 12.3 @ 114mph, Heathcote last Saturday. Thats getting there!

There wont be any secrets in the tuning. Will let you know if you are seriously interested. Real big horsepower cars are generally pretty manageable on the dyno. Just strap em tight, and lay in the boot. Cest la vie.

The factory computer though? Work of art. Makes ANY aftermarket system look like rubbish. Whats it do? Off the top of my head......

Wideband mixture feedback, positive pressure fuel and ignition tables (both high and low octane), programmable outputs (revs vs load vs temp), twin sensor knock retard (programmable attack and decay), long and short term fuel trims, adjustable injector scaling (able to cope with 8 x 1000cc injectors), closed loop idle speed control, twin cooling fan control, programmable traction control inputs, adjutable rev limiter (versus engine temp) for each gear, programmable shift light, decel fuel cutoff control, full auto trans pressure and shift control (should you not have a manual), 300 or so different error reporting levels, snapshot data logging, lean cruise algorithm, catalytic converter overtemp protection......and thats part of it

Best part is you can buy these computers for about $200 from spares shops

[MattR]

hmmm, sounds interesting

[whatsisname]

I agree with you Martin, GM certainly hasn’t dropped the ball from a performance perspective. My dropped the ball comment was more aimed at the piston slap and oil consumption issues that "some" owners have experienced.

12.3 @ 114 is bloody impressive from an unopened LS1. The 12.3 is obviously helped by a damn good suspension and tyre set-up, but the 114mph is amazing!

I am most certainly serious mate. I'd love to see the tuning and power runs take place.

Programmable shift light, data logging and programmable traction control, it sounds like GM had racing in mind when they sat down and started designing the system. And for the grand total of $200! Can it be made to run any engine?

[9krpm]

I am most certainly serious mate. I'd love to see the tuning and power runs take place.  

me too...pick me pick me :wassup:

hehe could you please add me to your invite list as well martin?

I would love to hear the supercharger whine on this beast :thumbup:
