great peak numbers!

although torque doubles between 3k and 4.5k... not really an easy driving torque curve but im sure its fast when its all out...

that's got to be the most power through the factory tit exhaust? Why the 60lbr's? Why not 80's?

nice numbers with LG's turbos. Wonder what mine would be if I turned mine up to 20#'s

Isn't there a major difference in spool up between the CHINESE turbo's and LG'S? How much rpm's later do the LG turbos hit peek boost at say 20 lb's?

I too am wondering how much meth is going in it. It's obvious the meth is offsetting some of the fueling requirements so it is a lot.

What are the LG upgrade turbos? Are they replacements for the GT35's or the mits. turbos?

If you have a correct fuel system built and ran a boost reference regulator then the 60s would be fine.

You guys should take that catback off and run it with no catback just to see how much it is holding you back ( would be a sweet comparison)

well obviously these guys arent engineers, nor are they responsible tuners. any engine running at 1040rwhp requires much more then 60lb injectors even at 100psi of boost referenced fuel injection. so take these numbers for what their worth... nothing (internet truths are rarely legit). either way, if the numbers are real, then they used an enormous supplement of meth which constitutes an unsafe build. in the event of a meth system failure, the motor will blow within milliseconds.

P.S. if you guys have conquered the laws of physics you deserve a nobel prize... let me know and ill nominate you.

Let me clear this up for you ... The only reason that I posted this in here was to show everyone that had a APS kit and was thinking of doing the LG upgrades that they will make the claimed 1000 rwhp that LG says they will. This car was built for a customer that was looking 800-900 rwhp with great street manners(he is in his mid 50's). When we first built the car we used the stock APS Mitsu turbos and ran them as far as they would go and only made around 820 rwhp. This was enough but after reading about the failures and oil problems with those stock turbos we encouraged him to do the upgrades for reliability. He agreed so thats what we did before we damaged them all to hell. Once they were installed he wanted to push them a few times on the dyno to see how much he could make. We pushed them and pushed them until we made the 1040. When we were done he was happy he had him a "Trophy graph" or as some say a conversation piece and we turned it back down to around 14 psi (850 rwhp) and he was a happy customer. No were in my OG post did I say anything about this being safe to let a customer take and beat the **** out of or if the 60's were the right injector. I just posted a graph to show what the LG's are capable of doing. If he wanted to run at this power level 24/7 then yes we would have gone a diffirent route and fyi at the 1040 rwhp level on this particular car there was no sign of the car trying to lean out. There are plenty of people on here that can vouch to how safe we are when it comes to tuning a customers car. I hope this helps you out.
