Well thats SEMA done. Spent loads of time standing and talking to everyone on the efilive stand. Learnt loads from Jessie (wait4me) plus from Ross and Paul about Duramax diesels, finer points of the software etc.
There were far too many shinny things like the new LSx GM Iron block etc.
Anyway back in the UK all is well, its winter and the car is idle in the drive. I have a few plans now.
Basically I got a power run and was only 80bhp off two brand new Z06's so while thats good, its not good enough. The power run was marred by the dyno operator flooring the engine at 800RPM, 100% throttle in 4th. Ive never tuned it there, so 4* of timing was pulled across most of the range. Im sure that dropped me well down the scale.
I have also purchased second hand a set of 1-3/4 4 into 1 headers with 3" collector to replace my current set. The aim is for a full dual 3" exhaust.
I'm going to get my emissions level checked to figure out if Ill need cats, then Im going to get it dyno tuned fully across the entire spark map. If I can unlock more power then perhaps I dont need to take the plunge and BUY A 416 CUBE STROKER!
However the likelihood of coming that much closer to a Z06 is pretty small. I suspect that a new engine is going to be required.
Im also now the proud owner of a Nick Williams 90mm throttle and Fast90 intake which I collected at SEMA. So with exhaust, proper dyno tune and the intake setup. I'm thinking Ill be getting a lot closer to the Z06!
My current quandary is do I get new heads and intake or keep my current ones (Which will be restrictive on the larger engine). Im pretty sure I already know the answer to that.. It just means my Fast90 will now need to be sold off along with the heads and rest of the engine.
Anyone in the UK want a nice stout LS1?
However before going to crazy Im going to dyno tune and fit the 3" exhaust and re-evaluate things. Coincidentally this might just well nicely fall into when Patriot performance get their new CNC L92 heads done. Im also hoping its when the US dollar falls further, hopefully past the $2:£1 mark.
SDPC has the 416cube L92 stroker at $4495, not bad at all!
Tuning has stalled somewhat with all my traveling. However after talking to Jessie I'm going to play with my idle a little more. I think I can make it smoother.
Next planned updates will be to report back on emissions tuning and realtime dyno tuning.
