Well things are finally coming together after I got a 2nd job to finish up my car. Still got a little ways but still coming along pretty fast... But I want to know how much boost I can throw at it before I start running into problems... There is not going to be any kind of street tune for it. I want all it can do all the time. Besides it's just a weekend cruiser, so when it will be out it will be looking for a kill.

What I have right now in my possession.
4.030 Block Callies splayed mains with arp studs 1/4 filled
4340 3.480" Stroke crank
4340 Eagle H-Beam rods (L19 Rod Bolts)
-22cc Dished Diamond pistons / total seal rings
62cc TFS heads (off the shelf will have them CNCed when funds allow)
A.I. Custom Grind cam (hopefully coming soon if not I will look else where, been waiting a month already )

Real Quicks Log hot parts
Ebay FMIC 32x12x4 3.5" piping
TC76

If all goes well it should be up by Aug. Also swapping to automatic TH400

 

What head bolts/studs?
Head gaskets?
Static / dynamic compression? (I'm too lazy to look meself)


Boost is restriction, ask how much power can you make.

That being said. I think you can run the 76 until its out of steam with a good tune and fuel. 750-775 to the wheels at 15-20psi?

 

What fuel? Octane will dictate amount of boost.

-Scott.

 

x2, are you planning on using race gas on the street? It will allow for another 20-25% of boost than with 93 octane.

 

I will be running a mixture of 90 (the highest around here) and race fuel. So I say 95 octane. Going with the felpro 1074 head gaskets, ARP head bolts. Aiming for a low 9:x.1 compression.

On a side note I got the specs of my cam today. Should get it sometime next week !!

Next step it to built the drive train around this setup.

 

I know a surefire way to find out... but you might have to change your name to BLWNUPLT1

 

Im curious to, Ive got a similar motor setup with Mahle pistons instead and Im usign APR head studs. Im also on a PT88 if it matters. I was planning on pushing 20lbs on high boost.... think itll hold?

 

only one way to find out. start low and creep up on the boost slow.

I just put a Novi 2000 SC on a 383 lt1. gonna see how far it will go.

 

You should be able to do 140mph on 15lbs, how fast are you wanting to go?

 

I want mid low 10's then cruise the car home and call it a day. No trailer queen here.

On a side not I got my A.I. Turbo cam

216/219 on a 114
546/549

Waiting on a few odds and ends then it time for assembly. Main problem will be tuning. There a shop about an hour away that does tuning but I will have to switch to OBD1. Finding one should be no problem.

 

20+psi on e85, add som extra meth and skip the fmic.
On oure F1 383 we had 17psi boost 2006, widh the same pulley, bigger cam, no fmic and meth injection we saw 20+ psi (boost gauge didnt go higher). No problems for 3 years widh that setup (have run it widh 60-125hp n2o 07-08 season, did 9.51 146 widhout N2O this spring, raceweight is proberbly near 3700lbs now since it has fullcage.

 

mid/low 10's shouldn't be a problem on lower boost. I went the times in my sig on the stock heads/cam with 11.5lbs. With some le heads and a xfi268 cam I went quicker in the 1/8th on only 8lbs. You should be able to go mid 10's on 10lbs easily.

 

Lisa,

Can you explain your thoughts on this? Obviously you have pressure loss through even the most efficient core and added weight/complexity - But if an IC is 70% efficient then you are taking say 0.7 X 200F = 140F out of the air before you spray.

Is 140F reduction worth a typical ~1-3psi loss? Or just run the compressor at a high efficiency and spray 'more' fuel/meth?

Thanks,
Scott.

 

Id like ot know also. Im at the stage right now plumbing the col side. and was debating a FMIC of a meth kit.

 

A FMIC is a lot better in a street car in my opinion.
