Nice, good to see another commodore with a 1UZ!

If you really dont want to use the return line you can use a pump and regulator near the tank, many new OEM apps now use a return-less system. There are advantages to this however it is probably easier to just use the standard regulator and add a return line. Without a return line or regulator...

Extractors have this venturi/scavenging effect at the collector. Venturi's in the exhaust stream are also comonly used as crankcase oil breathers on race cars.

Funny, I was thinking the same thing after reading your post. ummmm not when we are talking dyno's its not. I can assure you a dyno measures torque and calculates power. A chassis dyno like what was used in the graph posted uses roller RPM and torque on a load arm in the retarder to measure...

toys, first up take a chill pill and mellow out some! Now, a dyno measures torque not power, horsepower is the calculated figure. So this torque measurement will change depending on gear ratio and you get a figure that represents the wheel torque like in the graph posted. You have already...

Do you reckon its this one.... http://lextreme.com/forums/showthread.php?t=3588&highlight=prelude

I take it you have never heard of gearing Toys?? The 1566lb of torque is after going through a 4.11:1 rear end or whatever a R32 has. A T70 is gonna be pretty lazy at 7psi, wait till its boosted and it will be far more efficient. In any case thats a great result at low boost. And getting...

Cowboy - If you do find out how the VVTi is hooked up or if it is just disabled be sure to post it. Peewee - Yeah thats the only two i could think of, but there are probably a few less known ECUs around that also work. The other thing to note is that the exhaust and intake cams are...

I was doing a bit of reading and came across a pdf of how the VVT-i works on a 3UZ, it will also be applicable to the later 1UZs. While it uses the oil pressure it works the same as most other variable valve setups and should be no problem for a high end aftermarket ECU that supports VVT as it...

Cheers for that.

I had a look at a picture of my trans when it was out of the car (not a hope in hell of seeing it now its in the car) but cannot clearly see the cast identifier - can make out the U and it looks like a 1 but cannot be sure. It is a crown slip yoke box. So can anyone confirm it would be a U1 on a...

Do you know if it is cast into the bellhousing?? If so i can check whats in my car now and source the other style.

think you mean LS1!! Work of art none the less, there is a website with even more photos, i saw it a while ago and will try and find it again. Its even got a carbon fibre dry sump setup.

Is a Crown U1 or U2?? I am using a crown gbox and have the engine mounted flat, so have had to make the gbox crossmember allow for it.

Welcome along warpspeed! This what a few drag racers did way back in the 70's, my mate had a 727 torquflite with a clutch :bigeyes: Havn't heard about this one yet but sounds interesting, before the launch of the AWD HSV's they stated there will be no manual option on the AWD vehicles (power...

I like the disclaimer "Mileage performance is not typical of all lexus vehicles" :)

Could it be due to how it is dyno'd?? I have had more to do with dyno dynamics than dynojets but i know it is possible to get vastly different torque curves depending on how it is run up. My theory is that due to a dynojet not being able to hold the engine at a particular RPM/Speed, you cant...

PDA is Personel Digital Assistant, like this..... http://euro.palm.com/no/ There is now a locally built performance vehicle here in Oz that has one incorporated into the centre console that communicates with the factory PCM to give realtime engine stats and data logging. If anyone is...

How do you find the knock sensor part?? After reading up on it thought it would be pretty finicky to setup depending on the particular knock sensor. Do have any other info about it?? Yeah thats true, there are some pretty neat programs around for that. The LM1 i ended up with does...

Thanks Lex, yeah thats why i got this too... http://www.innovatemotorsports.com/products/lma3.php With the latest firmware it is meant to do even more than whats listed on the page. Will let ya know how it goes.
