I was looking at forged 4140, not cast. I would not run a cast fly wheel on anything except maybe my tow vehicle.

Great, sounds like you are heading the right direction. I have drilled stock crankshafts for 8 dowels with the engine assembled but it takes patience and a little effort . It is a lot of fun for very little money at that level of racing , we have had a blast doing it since 1985 .

Thanks for the advice.
I been researching as much as I can, nice thing is parts for these are pretty cheap compared to say my bbc in my malibu. I was looking at Porsche axles. The trans in it now is supposed to be out of a early 914 but I can not confirm that, it is IRS and looking on the bugget and a samba they make some good axles for these. They are not as strong as the swing arm style though from what I read and this trans has 2 case ribs? and one of the things I read is you want a van trans that is 4 rib? Not sure about that.

This thing has what vw guys call a freeway flyer transmission. It is supposed to be a pretty good unit. still have not had the funds to get her to the track yet.

When they talk about the number of ribs on the transmission case they are actually talking about the transmission from a late model VW bus. It uses a larger outside diameter ring and pinion so it is stronger than a type 1 trans like you have. In order to put one in your car requires some special mounts / parts but is substantially stronger than a type 1 trans.. I have a 400 plus hp turbo car and I am still using a type 1 transmission but with the swingaxle setup rather than IRS like yours. Both are good and both can be made to handle a lot of HP. To me the clutch package is more important than the the transmission. The free way flier usually means that you have a higher gear ratio 4th gear . What I would recommend is a 3.78/2.05 stock main shaft trans with the 3.88 ring and pinion , all stock parts. I use stock 3.88 r/p in my turbo car so they are pretty tough .I will be happy to point you in the right direction on anything you want to do VW wise , maybe even save you some money .Mike McCarthy

yes the high ratio 4th gear is supposed to be better for 1/4 mile then the other or so I was told as it lets you run it out the back better then the bus trans. Not sure if that is true but will get her to the track next friday and see how she does. I am not expecting much with a stock engine and trans.

Sounds like you are having fun at the very least. Are the tracks you go to all 1/4 mile ? I have never run a 4th gear that tall in a race car before , but I was also not running a stock engine either so my opinion will not help you . Something to think about is removing your fan belt in the staging lane and run the car down the track without it . Stop after your pass and put the belt back on, very east to do and will free up some noticeable HP .

yes both PMP and bandimere are 1/4 mile. I did not know about the fan belt deal, I will try that. thanks.

so I have the turbo for the turbo build and have the holley 2bbl carb got my eye on the intake manifold it is a draw through. so starting to get ready to turbo her. I got a fuel issue it is getting a lot of fuel in the gas. I believe it may need a regulator the pump is a vw specific low pressure pump but it seems to be flooding the engine. any way that is all so far.

I would definitely run a regulator . The Chassis Shop makes a nice manifold , there is no dip below the carb for the fuel to puddle in like some cheaper manifolds.

this is the manifold I use on 4 barrels carbs made by the Chassis Shop .

That looks like a 4" inlet , what size inlet do you have on your turbo ? It is hard to tell if the inside of the intake drops below the round tube or if it is actually flush with the bottom in the picture. If I come across an intake cheap I will let you know. Mike

it is 3" where it goes to the turbo and my turbo has a 3" opening. I am putting dual carbs on it for now, while I gather turbo parts.
