The 10.99 Upgrade Is Coming Along!

[gasketmaster]

I had hoped to get the minivan out this season but it's looking like it will be early spring before it's making hot water

My trans is back.....fresh and ready to go

The FM converter had about 20% slippage previously......it has now been reworked

The new shortblock is assembled and ready to go with forged pistons,ARP fasteners and all of the required machine work

I've decided to give the 655 casting a try because I've had good luck using larger intake runner volumes in turbocharged applications in the past

Here are some pictures of the head....it's coming along!

Holy crap, those ports are huge,

Looks like your making it a swirl/g head hybrid,

What turbo?

Whats the track limit without a cage or rollbar?

Yes.....those ports ARE huge! LOL!

I'm sending my ballbearing 50trim turbo in for an upgrade

A rollbar is required at 11.49

Wonder what a Van rollbar looks like,

Wonder what a Van rollbar looks like,

I'm not sure just yet how I want it installed but it will definitly have swing outs

[gvare001]

What are you doing for intake manifold?

Wait unitl spring

Gasketmaster- do you reshape or trim the guides before installing them?

[glhs875]

That looks so much like the head on my GLHS it ain't funny!!! With proper porting that head should make BIG HP!!! What are you doing for an intake. I had a 2 piece welded so it could be ported enough. I plan on a full blown custom intake in the future. The power that my GLHS made @ 30psi with an SC6152 turbo scaired the crap out of me!!! It made me decide to up the safety of my car bigtime (cage, better brakes, seatbelts, etc.)!


Here's a couple of old shots of mine to show how similar yours is. Mine looks a little different/better now since I freshened it up.

655 is a nice head. I know what he's doing for an intake. Although I think he should go with a 58mm TB vs. the 52. But oh well.

The intake looks kinda like this



Thanks Jay

See post #10

[glhs875]

That intake has some potential!! Have the runners been ported to match the head?

Sometimes we trim them....it just depends how far they hang out in the air stream.

That is a picture of Jay's intake

He made me a plenum just like that only I don't have the spacer between the upper and lower

My lower is getting welded in a few places so we can get it out to the largest cross-sectional area we can

Have you dynoed or ran your combo at 30psi?

[BadAssPerformance]

Lookin' good Terry! Damn, thats almost enough to make Simon want to go 8 valve

[glhs875]

Have you dynoed or ran your combo at 30psi?

No, neither. The highest boost I ran was staged (3) to 20psi. And that was with the bov limting boost creep (I know not good)! The swingvalve could not bleed off enough exhaust to control boost above 5500rpm, it became uncontrollable after that point. I've since have been fabricating an external wastegate. All I can say is, that with an S3 cam I never did find the upper rpm power point. Had it as high as 7800rpm but was running out of valvetrain. Broke alot of valvetrain parts. The valvetrain is mainly what I have been concentating on. I hope to start back to work on the GLHS this spring after a 2 year break. We'll see. When the boost would hit 26psi from boost creep in 2nd at around 75to 80mph the tires would break loose. I made 1 pass @ 30psi in front of the house in high gear only. Went from 50mph to 100+ in well less than 1/8th mile. I still have some things to work out with the combo.

Here's a coulple shots of my lower ports. I since have done even more work to it.

Not in a million years, his combo might be awesome but I love mine, the midrange and throttle response is insane and I haven't done any tuning yet,

getting 40mpg yet?
