Default Congrats!

Hey Doc,
Now your not messing around anymore. One small problem, once you get her done, you will never want to build a normally aspirated engine again. You will have seen the light!
Only other words of advise I could give you would be to be patient. Turbo motors are a little more complicated and usually take some time to work the bugs out. Hopefully not but it usually longer than you would expect. It is worth it though. To me, an engine without a turbo or centriificalsupercharger is like a dauy without sunshine.

Rob

As a side note I may be selling my spearco If anyone is interested PM me. It will support 1000 HP and was on chris capri well into the 8's.

I dont think I will have the room with the lift off nose to run the pipeing and still be able to remove the nose easily.
I think I am gonna go back to water meth.

Yeah, I agree. I have not seen another intercooler like that one ever. It's even dual feed intake.

Thats some intercooler. I am going the meth injection route.

Rob, You are right about the turbo bug. I dont think I will ever build another NA again. I know it will take a bit to get used to, especially so much power on my first turbo build.

I think it will work fine but, not sure how you will hide it though?

Maybe Mark would like it?
That is a big one but check out our icewater unit. It's two 3000hp cores stacked on top of each other.



Frozenboost.com has some pretty good deals on intercoolers. I know they're Chinese or whatever but I've only heard good things so far.
I think that meth injection maybe a good thing. You can also put some nitromethane in the meth tank to juice things up a bit.

Update time.

Simple, I got the motor back today and dropped it in the car. Waiting on pushrods.

Tommorow I will get time to start the header fabrication. It will be an challenge as I have never done them before.
A couple of notes.

The clearance now with the convertible exhaust is increased a good bit as expected, 5 inches to the steering shaft.
Before there was 3 1/8 between flange and crossmember. You could do logs if you want with that clearance.

The 5 inch down pipe fits with no problem with the ac box out with the standard oil filter. Just need a 90* fitting for the pressure line.

I am going to try to do this with the Power steering. Manual brakes. That means the collector will be high on the drivers side to cross over the upper rad hose. Going underneath will restrict air flow from the radiator ( when combined with the other pipes).
I will say the convert exhaust really makes it a much easier task.

Some pictures tommorow.

The 20cc would get you closer to 10 to 1 and the aluminum heads react like 9 to 1. With an intercooler that is a doable compression ratio. If you go to a blow thru carb the carb also adds a cooling affect as the air goes thru the venturi and brings the atomized fuel into the mix. This whole combo can run 9 to 1 easily. If you use racing gas (assuming a race car not full street) then you are in like flint. I run about 9.2 to 1 on my .030 455 with 6X heads at 97cc. I ran my TA on the dyno with swill 91 arizona gas, a too small air to water intercooler and the blow thru and ran 15 psi boost without a wimper. The shop/dyno owner stationed himself next to my motor to listen for detonation and said he heard nothing. He's an import and Mustang tuner and was very suprised at the numbers and the tune on the car for an archaic old carbed car. I do admit that the blow thru was recording WOT a/f ratios of 10.5 and 11 to 1 during the run, a little rich and probably help with the safe run. Mark L

Thanks for the good information..it helps. I'm running 10.80 compression now with 16 cc dish and a .050 head gasket. Not sure how much more of
a dish piston I could run.

No one home yet so I will keep going. Hopefully I will get them both done.
There is alot more room than I anticipated.

Looks good Doc. I was out getting this in order tonight too. Got that king sumo in and got it to idle. Needed alot of throttle blade opening with or with out the IAC.

changed the compression in the tune from you 10.75 to my 8.2 and that seemed to help alittle too.

I need to get a 3 into 3.5 reducer for the spectre hat still my old hat wont clear the throttle linkage. (man I wanted to keep that steel hat)

Runs good nice and crisp. Of course its still an N/A tune at this point. I am hoping to get all sorted out for next weekend and maybe chris and I can work on tuning it.
Job wont touch it if I go water meth Injection.


I am looking into using the accesory injector as a water meth deal.

BTW what the F is a carberated car doing with fuel rails?

Good catch on the fuel rails. That is Obviously my FI manifold. The only other manifold I have is the Dominator flange and I do not want to use an adapter. I have a set of billet injrctors to plug them up. The maninfold is gasket matched and polished. Do not want to spend the $ to replace it with a non FI right now. Have to sell the 2 I have before I officailly have a collection of CV1 manifolds.

First I ran out of mig wire, then pipe. Now have to wait till Thurs or Sat to finish. Doing all I can to make E town.

I knew that already I read it on TTF I just wanted the guys to know too.

Its amazing how much wire you can use making a set of headers isnt it?

Pipe too.

People dont understand what goes into making a set.

Looks good Doc! One of the toughest parts of doing a build is keeping your parts supply flowing! I spent alot of time pre-planning and ordering parts, if your short 1 pipe or bend it can stop you dead in your tracks.
