one of the drawbacks of blowthrough... any leak before the maf won't really be noticed until the turbo is overspooling and you can't build boost.

I read an SAE article a while back about this subject, but I feel like a big part of this debate should focus on flex, and not just vibration. a 4cw crank is not used in many production engines rev...

Here is the product so far.

Needs some porting work, no biggie.

I called it!

It is worth mentioning that K20s come with both cranks as well. The 160hp version of the K20(A3) is a 4cw and revs to 7K rpm. The Fun K20 (The A1, A2, Z3 etc) rev to 8 and 9K and have 8cw cranks.

Sounds like an axle to me. I could still drive the car around a parking lot just on LSD alone lol. It would barely move though. I have only broken 2 axles so far.

I have run .032 easy and didn't start to cut out until over 20psi of boost. 22psi was the most she could do with copper cores, Iridiums were able to hold over 24psi on the same gap!

I think they would work great for turbo, but wow are they expensive. They are pretty aggressive also and may require springs to rev high...

I squished the top of mine until it would hold 22inHG vacuum. This is an increase of nearly 5inHG over stock. I don't leak anymore and the turbo will push over 26psi. The BOV may be leaking at that...

So how can we order these? from their site? I think I am goin to start saving some pennies. The N1 cams should be good to what? 9Krpm without springs? I don't want to go any higher than that.

if you have the right stuff as listed you can run it no problem.

Put it together tightly enough to not come loose, not so much to break the screws lol.

Just make sure you use the right drive ...

I swear by the DSM or factory nissan. The crushed DSM has been very reliable for me, with barely a hint of surge and holds up well to boost. Plus it was free. I don't see the sense in buying a 100+...

gee whiz how far did you crush it?

I have had very very little compressor surge. You must have had it crushed too far or your lines were not hooked up right because there is no way a crushed dsm e...

if the car doesn't move, I doubt it is the clutch at that power level. Most likely the axle snapped.

You have to put the BOV in a vice and crush the top of it slightly so it will hold up to more boost. Look up on the DSM forums for more info. I just preloads the spring. There are other ways to mak...

any regular DE pump will work for you. Sounds like there are some issues... I would take the old pump apart to see what is going on.

sounds like it glazed over pretty good. I've seen a few high hp cars completely melt down clutches the first time at the track. How much power do you have in that thing? and ACT should handle 400wh...

I had to crush the dsm bov so i get just a bit of flutter at low rpm under load.

I have a built VE. GTIR oil pump kit from GregV. No problems here in over 14K miles of torturous abuse.

I wonder if taking the rubber out and replacing with metal washers will cause permanent damage to my spine... I already have a pretty stiff engine bay.

Like Ben, I too am using a 1G DSM. I love it. I crushed it a bit instead of drilling ports etc. I have gotten it to hold steady at 24psi, it just barely barely seeps at that boost level.

It is q...

high mileage cranks have been known to bend slightly over time. Not sure if the SR crank has that issue with time...

I have a VE with an 8cw and it is very smooth up high. Sounds great. About th...

Have you thought of putting the BOV on the hot side?

I guess I should add that a friend of mine switched from Blow-thru to pull-thru last week and he says the response isn't as good, but the ca...

The mafs with a screen on them will work a lot better in areas of higher turbulance. The Screen promotes good laminar flow.

I would go about where you said. 12" away from the TB, and try to keep...

Sweet. Can't wait!
