365rwhp 351tq
Here's the latest dyno of the sky... big turbo.
21,23,25 psi pulls. as you can see the computer went bonkers on the 23/25 psi pull at around 5800 rpms, it's due to 'limp mode' when it sees more then 23 psi for 3 seconds. Still trying to work around that... but its certainly got 375rwhp on pump gas in it. 400+ at 32+ psi on race gas. Ignore the tailpipe afr, it was awfully off. The factory wideband and AEM UEGO both read 12:1 richening to 11.7:1 or so at redline, where the car was tuned to.
More to follow once I get around the limp mode issue... this isn't in a cobalt, its in a sky... but just goes to show the potential of this motor once things are becoming unlocked in the pcm and aftermarket turbos are being bolted on. Hopefully the added market the cobalt brings will accelerate development of parts for this engine. I'm on the sky and solstice forums as 'GhostRL'

great numbers though, seems like it has more in it from the other runs

Right here! This won't happen for the SS/TC. Tranny, Tranny, Tranny! The Kappa's have a different tranny. The F35 is rated to 258tq. You won't hit 400hp on the F35 without some major work, or even a new tranny all together.
Don't get me wrong. I love the LNF, especially in the Cobalt. Even I want one. But people need to start being realistic. The engine may be able to handle it, but the tranny can't.

right here lol.
can't wait to see what my car will make on 25 psi since I made 411 on 21.5psi.
but nice numbers man, can't wait to see what it does once someone cracks the damn limp mods bullshit. I have a few locals that I want to work with but I won't touch the cars until I have full access to the pcm.
my trans is still fine and I"m above that in TQ for months now, granted I haven't taken it to the track, but I've beaten the living hell out of it for months now and it's still all good. no to mention the numerous passes I made on slicks with the s/c on the car.

So this "lot of work" you mention what does it involve and is it something the average srt-4 owner is doing? Hell even find me 3 people making over 360 on there stock tdo4 no Sray and by all means links to the graphs and threads would be nice.......

this is not big feat on a modded stock turbo ( ported and big wheel) but for a bone stock turbo 300 is usually the limit.
