Picking up the Stage 2 Vert from GTM!

Armonster

Very nice! 2 questions:

(1) How are your temps? Could you tell us about what kind of temps you see and what the ambient temp and your driving style was like at that time?

(2) Do you notice any additional vibration in the upper rpm range? The issue of vibration with stiffer motor mounts was brought up in another thread, but I wanted to hear an independent opinion.

Just an FYI, while the car is in Colorado it may run a bit hotter than normal. I don't know if its the lower density air or the lack of humidity but engines run a bit warmer than average here.

Have pretty much stayed out of it for the trip. I jus drove a constant 70-80. However, OAT's have been high, density altitude has been high and I'm pulling mountains. So we are in Denver now, so we will check the milage on flat ground. I have been running a very high oil temp at times. In the 240-255 range. I want to see what happens when I'm not climbing hills.


See post above but the temps have been running on average 100 F outside. No extra vibration while driving really. Just pure enjoyment to drive!

Sam has one he is working on that I got to see first hand. It is a work of art. I will be going this route next year.

Agreed


All in all, sam and the crew at GTM are top notch in my book. Even though I was a pain in SAMs azz at times, he remained professional at all times and that professionalism carries over into their work. I am very impressed with this kit and the quality that went into it. Sam and GTM will continue to have my business as far as I'm concerned.

Sam,
Will an aftermarket radiator fit with this kit? Since I'm in Florida, the extra cooling would be ideal.

I really love the sound. Is the whine as noticeable in real life as it is in the video? and... that BOV WOW.

Last mountain fuel stop I got 22.40 mpg. Next fuel stop with be flat Land tips on the last leg were upper 90's averaging 55/80 mph

jezzz, you're making way better fuel mileage than me, and I'm making way less power than you lol. Last long trip I took i made 298 miles on The whole tank driving normally.

dixon cider

Ouch. I have been refueling around 260-280 miles and still have over a quarter of a tank.

yep, i'm getting ready to kill myself pretty soon! seems like everybody with this kit is averaging over 300 miles on a full tank of fuel. i've only seen that once when i first picked up my car from GTM. oh well.

dixon cider

The odd thing is my fuel computer is WAY off. Every time I fill up, my range to empty is around 606-610 to empty. It was not like that prior to the SC. Don't really know why. But I know I will not see that out of a tank even if I pushed the car for a hundred miles first. Trying to race hail storms here in Kansas. Don't really want to get caught up in that. 1187 miles so far.

Haha, my car averages 30+mpg sometimes according to my "fuel computer"...then reality sets in when I'm on empty at 250 miles.

Not problem at all.

The fuel thing has something to do with it reading the pulse from the injectors. Now that you have changed them to something bigger the readings will be off.

Yeah, we have been discussing that in another thread. The current theory is that the ECU is calculating fuel use based on pulse width. With bigger injectors, the pulse width goes down relatively, since a shorter pulse on a bigger injector gives the same amount of fuel. It would be nice if that was a parameter that could be programmed, but it seems like at this point it is not.

Regarding fuel mileage in general. Does the SC use a clutch? I.e. when cruising along at 70 are you making boost or is the SC freewheeling? I would think that you should achieve near OEM MPG if the SC was effectively decoupled when not accelerating.
