NIevo,
You should REALLY consider bringing the car up here for a few days and getting pistons/rods done to the engine. It's a lot cheaper to do it now instead of later.
The finish line RPM is getting up to where I consider it not very safe, atleast not for very long. Just take it into consideration.

good eye, I missed the 8300rpm reference. what do you considered safe for extended use? I twist mine daily to 8k and have been for about 14k miles and countless drag/tuning runs and autox events. Seems like I'd start seeing bearing material by now if it were a major issue.
I haven't had the need to go higher than 8K with my weaknut trap speeds on pump gas but I might be tempted to when I put in the jesus juice (c16) or meth and finally let the 20g do it's thang
I really dont take it that high very often. I do no racing on the street and have only had it to the track twice with the 35R. I only took it to 8300 once or twice cause I was tired of bouncing off the rev-limiter, but I still hit it
I turned it back to 8k after that.
nice numbers....I will be putting my buschur 35r on my car this month. Just pump gas for now. In feb, I am building the block and adding meth. Just me something to look foward to.

Finally got the tune alittle better and broke into the 10's in a big way! First run I was seeing 11.3-10.7 AF/R's and 17* peak timing. Knew it was going to be a good run when I hit the rev-limiter in 4th about 20ft from the end of the track. Looked like this:
60' 1.65
1/4 10.80
mph 129.28

Second run a roasted the tires and ran a 11.22@130mph with a 1.89 60'. Finally the third run I knew it felt good out of the hole and even after raising the rev-limiter to 8300 (I know, thats pushing it on the stock internals) I hit the limiter about 50ft from the end of the track. AF/R's were 11.7-11.1 and peak timing at 18*. Here's the breakdown:
60' 1.62
1/4 10.61
mph 131.59

I was running a 50/50 mix of pump and 110 and the meth injection. Running 29lbs boost and seeing zero knock across the board. Traction is really an issue now though. I was either hooking good or just roasting them, its a very fine line. Pulled several 1.9 60's as well.
Is this the fastest ET and mph on a stock block so far? Big props to Buschur either was for making some amazing products at unbeatable prices
Video's will be up in the next couple day's.

I think some of you guys are UNDERestimating these motors. Few people have gone a bit faster (MPH = 138), ran much more boost (38psi) and even revved higher (8,700rpm) on stock 1G DSM 6-bolts. I expect EVOs to be a step ahead with a 15yr technology advantage.
Great times man! Good luck in '08.

I think you are too hard on him. The 4G63 REALLy can take a lot more power then you think. The issue is knock, any significant knock and yeah it is toast at that boost pressure. A Mr. Sean Ivey has been pushing nearly 600WHP on his STock bottom end 2003 Evo for a couple of years now. It is fine, really. The RPM's may be an issue but then again, Ivey has got it to 8700, these motors are VERY VERY good and if tuned properly will last a VERY long time.
