adam, i know you went this route but there is a reason why the Big 92mm DBW do not have the same comprimises as the old TB. The old TB are basically a cylinder. GM (and bosch and the rest) learned from this and made the big DBW DB different. Hard to explain so hopefully this pictures shows...

Don't have to. Fluid Dynamics is what those books are based on. ;)

still in testing and no official date set for release.

you are forgetting one important thing. It is not pressure that dictates pressure delta it is volume in relation to the area which is actually tied to speed of fluid ;) The key words are critical Velocity, which once attained can not be surpased. That is why even air obeys such law and why...

Gauging intrest threads? Sorry no. thread closed. Send GrimJack a message about applying for group buy. Intrest threads are only dreams and never turn out well

That would be a G-Force/TechTom ECU. Reg Reimer in Canada still might be able to tune that for you but it is getting more and more difficult to find someone to tune those. http://www.technosquareinc.com/romtoyota.htm TY64A on top ;)

the more important question though is what is the pressure loss incurred by the OEM fuel rail when flowing that much fuel to support 1k hp? FOr those motec folks, the answer is a two pressure sensors away. 1 within and inch of the fuel pump and the other right of the fuel pressure regulator...

forged + coating = win win. Adjuster did this. Works well!

Hey, I enjoy being proven wrong, the very little times it happens. Ultimate power can be done by any EMS to include the Megasquirt. Hell that can be done on a carb setup also. The real question is driveability. That is what REALLY sets EMS aparts along with reliability. The other question is...

adam, welcome to big bore throttle bodies. That is not only an issue on the Q45 but every single 90mm TB out there save for the OEM 92mm DBW setups from GM and Bosch. The only option is to live with it :( The bigger TB has more area when the plate opens so effectively acts like a...

No guage. Idiot lights. Guage means take eye off the road. Idiot lights as long ad they are within your field of view. You will know when something is a miss. There is a reason why racecars have more lights than gauges!

And moving this to off-topic....

A becNh racing thread on two cars the op does not have? Lol! Dead thread!

One third of the way up?? I see your problem! You need to get a guage to give you, the driver, ACCURATE information! The stock gauge is a bit lacking in that department hence why one of the troubleshooting steps is to attach a mechanical pressure guage to the port to verify proper operation...

Nosechunk, sorry about that. You are right i got you and the op confused on the goals. Though the number of drivers does not dictate how low can they go. Still a function of the Cpu, developers that coded the CPU and associated components (type of mosfets, their response, their specs etc, and...

come again? You are not making sense and contradicting yourself. A start at 700cc/min instead of starting with 1000cc/min injectors? You speak of not wanting "crap" you don't need but right off the bat, put the injectors in the double dip category along with god knows what else just to "see"? I...

same drivers? You perhaps mean same MOSFET but the MOSFET is not what dictates Inj control. The programming and the CPU does and particularly the sub 1ms control. I know of MoTec in the .75ms range with not one hiccup. Now you speak of money is no objec but yet talk about 7-900 hp and you...

summit jegs pegaus racing they sell hardlines and the nuts too.

South Dakota, wow that brings back memories! I purchased my 87 Supra in Rapid City, South Dakota back in 1994. :)

moving this to the turbo section as this is not an engine tech question.
