Where did you put the pitot? With valves or without? If with, lift, etc. I'm just getting ready to work a GE head myself :p From the numbers, looks like I'm going to need significant ammounts of epoxy, barely hitting .6 mach at 8k! Yeesh.

I used an LTX8 (LT10 with an onboard ignition) on my 3SGTE in wasted spark config. Software is pretty straight forward, easy to use. Responds well to part throttle conditions, I eeked out about 35-38mpg daily driving, mixed city/highway. Not at all drag only. Only reason I'm pitching it now is...

^ Cheap alternate is available. Modified Ford smog pumps to handle oil mist and run those for a light vac, are available and quite successful. Routing to inlet with a good catch/mist seperator is just fine for most setups, but a vac pump does have a number of benefits if you wanted to go that...

What exhaust manifold are you going to use for the test?

Story time! :nuts:

resize much?

Did you regap the plugs to a wider gap, or just leave it as set?

Because I don't need more than 300 in my grocery getter.

Your solution is the correct one (assuming a few things like 100% IC efficiency and 0 pressure drop), but the equation is a little off. It's not pressure ratio you want, it's density. Your can reduce the pressure if you cool the air, but the airflow requirement is still higher. Well, you are...

It's your rod to stroke ratio that determines the wave, piston position specifically. The plenum and runners control the timing of those waves, but the cams do most definetly play a role as the valve position determines how those waves are transmitted and reflected.

All of the above D-Dayve posted is correct, if you're working on a bone stock setup. Doward is correct if you have a system in which the exhaust backpressure is greatly reduced through either a big turbine setup or a specialized low reversion setup. But most folks don't use a ~>.80 a/r turbine...

So, in other words, you don't know the wall thickness, and you have no clue if a set of sleeves can be made to fit? Have you even contacted a company such as Darton to ask if it's possible to have a set made? Don't talk to me about best guesses, you have nothing to back up your statements. Your...

You're correct, I have no clue about the average wall thickness on the 7M, because the information isn't anywhere on this forum, or on any other that I could find. So in that case you might be right, but having siamesed bores has nothing to do with sleeving being effective or not. It does...

Yeah, read it in a newspaper :thumbsdow Siamesed bores have nothing to do expansion properties or stiffness of the sleeves, and yes, chromoly sleeves would certainly stiffen the bores and prevent distortion under that kind of load. :icon_roll

Meh, if you want to throw enough money at it, you can make it reliable. Lets see... for a daily driven 1kwhp... Filled dry deck, head tapped for external lines, freeze plugs removed and tapped and water manifolding installed, blockoff installed @ stock water pump location and external...

Noone can tell you why? Hell, I take take a guess just from reading how the engine failed and the fact that N/As live. It's the oil feed distribution. Obviously the mains are the last to see oil. The reason the N/A lives so long is the lack of oil being diverted to the turbo so the mains see oil...

Accurate Injection is Kevin Thorntons screen name on hybridz. http://forums.hybridz.org/showthread.php?t=128314 Can't wait to see results :)

Any testing yet? On a side note, these are the ones Accurate Injection made are they not?

The groove between the first and second compression ring is to catch blow by to prevent the rings from unseating
