Question...
I have purchased a factory new block from overseas to replace the old us spec block in my playcar. The new configuration will be with ITB's, large cams, header, headwork, etc..
My concern is that the engine will see substantially higher RPM than the orig factory intended. I was...
I have seen the setups where you hook a line to a mount on your header and crankcase to create a vacuum. I have also seen a electric vacuum pump made for a brake booster that says it creates a max of 20hg of vacuum.
Can/will this make a noticable hp increase when hooked to a crankcase or valve...
I've seen a high mount injector kit to put injectors in the stacks of my ITB's. Has anyone any thoughts on this?

Maybe its just me, but I see an awful lot of people build a engine with lets say 11-1 pistons, but also put in large cams without considering that the effective CR is actually lower now.
How do you calculate how much different cams will lower your CR so that you can raise the static CR up to...
After talking with a friend, we are toying with the idea of essentially spacing the injector housings to move the injector tips back out of the middle of the intake manifold/port where we are pressuming they are causing a considerable air-flow restriction at high RPM (up to 7500+)
Since this is...
Ok guys.... heres the problem. The stock pressure plate for my car (aprox $45) has the straps held on with rivets. These straps and rivets are known to break at high RPM.
There are a few companies that sell modified PP's with double stacked straps and bolts instead of rivets but they want...
Well guys... I am getting ready to build a new head for my play car. I will be installing larger valves, tapered valve guides, lighter lifters, Ti retainers, springs, cams and porting it myself.
Is there any ideas of something I could do to the combustion chamber while I am at it?
Here are...
Hey all,
I saw an article on autospeed about using turning vanes in a cylinderhead. Has anyone ever tried this? I could not find any further information online regarding this concept.
They talked about using 2 little simple curved vanes to help the air make the turn in the intake port, and...
Hey guys...
I have been involved in a few discussions on a different board about lightened valvetrain componets, and was wondering if any of you had anything to say about the concept, or knew any article, etc about it.
Just for kicks, here are some of the threads we have been talking in-...
Hey guys..
I am having valves made for my engine with stems slimmed from 7mm to 6mm, and the heads .5mm oversized.
Is there much power to be gained from this? Any charts or articles about it?
Here is the thread with the info on the valves I am having made. They are for a VW 2.0 16v...
After lurking here for a little over a year, I figured I would sign up to see what you guys think about my custom intake manifold project.
Here is the link, with explanation of what I am doing, and with many pictures.
Thanks- Josh
