What, you want a build thread on my girl? She's going with me on Saturday to Mike's to dyno the big 3 tunes, I'll snap some pics of her with some No Limit stuff so I can justify putting it up on PSA, lol.

What sort of EGT drops are you guys seeing with just the atmosphere upgrade?

My street tune peaks around 1250°F which I like, but the hot street tune hits about 1550°F which worries me about the thermal shock of the stock pistons. Any major concern of the increased cylinder pressure if I still run head bolts?

you will need studs. with just an atmo upgrade and GH race tune i struggled to break 1500. was typically in the 1465 range. When i did the atmo and hp charger, ported intake manifold, no limit intake and piping i could barely break 1365.

Good to know!

Perhaps I will look at a better intercooler and BD manifolds to drop EGTs, until then I will just keep dorking around on the street tune. Not really interested in the out of control spiral that always seems to occur with studs.

I wouldn't waste money on an intercooler personally. mine lasted fine at 650+ HP. studs arent scary if they are done right. Morgan @ Midwest Diesel can help you out with and manifold and the correct tq sequence for studs.

Mkay, good to know. Thanks



Sorry for the hijack OP!

I've got a s366 and it seems better at WOT (stays under 1300 on Cale's street tune) and cruising speed (750 or so), but will get hotter lugging up a hill in overdrive or average acceleration. Still never gets hot enough to cause damage and performs good to me.
