1600 turbo build thread

I just don't want to get compression so high I will only be able to run 5 psi of boost

[rubenski]

Will be lazy off boost then...

Better a little more like clone says and fab in an intercooler or watermeth injection...

[buguy]

I would only be able to that if I go through with the blow through conversion.

[madmike]

You'll be fine up to 8:5 on premium mine starts to ping @12lbs. then I add some 110 race fuel

[buguy]

I'd be ok with 12 pounds. I about pooped feeling 11 pounds for 2 seconds!

[Chip Birks]

I'd be ok with 12 pounds.

We've all said that...
Now I'm gonna see if I can't get my little engine up to about triple that...
Its a slippery slope.

[buguy]

Haha!
Speaking of slipper slope.... I called Tim's today and to get my chamber volume where I need it I would have to get them ported. $670 for the pair. Owch. What other option so I have? Overtly large deck height? Find a stockish head closer to the cc I need? I'm going to use 92mm bore.

[buguy]

Wait! I miscalculated. The chambers on the Tim's heads are 57cc as cast. That would put me right at 8:1 compression with. 048 combustion chamber. That's better. They are $207 and I think another $20 to open them up to fit the 92 barrel each.

[Chip Birks]

You seem really stuck on that .048 deck height. Is that what you currently have or something?

[madmike]

Don't be afraid to run big deck ,, check what the Red Baron runs

[buguy]

No it's just kind of a middle ground.
Everything I've read says a tight deck is better.

[Chip Birks]

Its mostly about clean burn, cool running and efficiency. Red Baron doesn't care about fuel mileage, or cool running.

[madmike]

mine has .120 runs cool and 28 mpg with a 750 Demon doubt it burns clean though

[buguy]

My guy checked out the case and it is good to go without a line bore. So I guess I will order my pistons today. Really been struggling with what pistons to buy. AA are obviously quite a bit cheaper but everything says to get Mahle. Clone is having good luck with his but can I get a tune as spot on as him with a carb?? Maybe if I keep boost low until I get a better ignition system I will be ok.
I think I'm going to get a W100 cam ground on 112 lobes and maybe spring for some solid rocker shafts too. Maybe!

[buguy]

.120 and your still at 8.5:1?? Dang!
I think having the engine hanging way out in open air helps us keep things a bit cooler.
I've been doing some searching and reading and came across this from here last night. Thought it was interesting. viewtopic.php?t=102753
