Don't you work for Dudes performance?
Good luck with your project, we're ready when you are.

Re: 408 turbo LT1
Actually I used to work for Dude's...they laid me off because they couldn't afford to pay me, even though I got them half of their F-body customers...And My friendly bet is with Pat...Ask him....we were talking a few weeks ago about it and he said he wanted to get his new motor done first. I think it'll make for some fun racing, seeing a N2O car go against a turbo car. All in good fun, infact I was over there a couple weeks ago discussing fuel systems with Mike, since I Liked what I saw in the tank and stuff. But thanks for the luck...we'll need it to try and get this done by next spring.

Actually you INTMD8-recommended his converter, shift kit, and trans cooler upgrade.....Works really nice behind the 150 shot...12.17 @115, totally stock suspension. Too bad we're gonna use a 400 with a brake to handle a little more abuse than I think the current A4 will like.

Re: 408 turbo LT1
I e-mailed Ed and worked up specs via e-mail. He's one of about 4 people who know my entire setup. 
You can try calling him. We've called him in the past for Mustang cams.
1-3/4" primaries will work perfect if you've got a 1.60 exh. valve. Normally, you try to make the primaries 10% larger than the exhaust valve.

Re: 408 turbo LT1
thanks, as you can tell we're not too worried about who knows this set-up. And I was hopeing the 1 3/4 would work but I've got this strange feeling they may not be big enough....only because of the HP levels this turbo is capable of. But I suppose if we really crank the boost we'll probably shatter the block. So I guess being restricted in how much HP we can flow will keep the motor alive a little longer
BTW will the PTK kit bolt up to a PT-96 Garrett?? I've tried asking they keep telling me to call them and I really don't have the time between work and family right now.

Re: 408 turbo LT1
No it will not bolt up. The 96 is a T6 flange, the PTK system uses the standard T4. If you want an LT1 PTK kit, they will direct you to myself. So feel free to e-mail me with any questions.

Re: 408 turbo LT1
Well just did some reading on a single plane intake on an LT1...very nice. I'm thinking I would rather do that than try to get a 58mm Tb to flow the air I'd like. I can switch to the 215cc race heads and go with a Victor E single plane....everything's ready to go and I can put a 4 barrel 2000CFM T/b on it and get a little more flow. Plus the 215's flow better than the 227's. So current status
383
scat 7000 crank
oliver 5.7 rods
J/E forgings for 9.5:1
AFR 215 Race heads
Victor E intake
Edel. 2K cfm t/b
PTK Turbo kit probably with a Garrett gt47-88T turbo and air to water intercooler.
Plus the cam....still no idea....
How's it coming guys??

Re: 408 turbo LT1
You'll have better luck sending Jose an e-mail instead of a PM.
Also, the 1 3/4" should be more than enough header for the car. Anymore than that and the turbo will start to become sluggish.

Re: 408 turbo LT1
I'm thinking I may just keep the PT-96 as it leaves a little room to play with boost and HP #'s....I'll just have to change the Flange on the PTK kit and maybe move the radiator a little. All of which isn't going to be a big deal as it sounds since it will be mostly a race car. Fun-Fun. I guess all that's left is the cam...yeah!!!

The last time I looked the Afr 215's were like $1,000+ more then a 220 or 227. You wont need these heads to make the power you want, but it might get you there faster. The 1 3/4 primary tubes will be fine, thats what i use. I run 2 3" down pipes and dump them at the axles. I would think that with a TH400 my car would be in the 8's. However, its a street car and a daily in the summer, so I kept the 6spd.

Re: 408 turbo LT1
I'm going to talk with Midwest out here about the converter, they'll fix it if we put it in and it doesn't work like we want it to. And Can the LT4 Intake really keep up with all this CFM??? Actually can the T/B keep up with all the CFM I need it to flow for this motor?? That's the big worry I have right now.

Re: 408 turbo LT1
But will it make as much HP as a single plane?? I can have a sheetmetal version made dirt cheap, and add a 4 hole 2K CFM T/B. I'm pretty sure the SP will out flow the LT4 intake & T/B.
