Thought I would post the latest info on the XP-T kits from R&D Custom Turbo Werx. The turbo reeds are in the line up for programming and should be ready ahead of the original release date of late summer, early fall. The exhaust parts I sent off should be back this week and I can start machine bending them on a computer aided CNC mandrel bender for consistancy and repeteablity. This is better for me because I don't have to hand build all the tight radius bends in the exhaust and for you it makes a cleaner looking kit. I hope to get one final test in within the next couple of weeks so I can also get some video for everyone
. Should have 2 XP-T's (1-154" and my 163") and I'll also take my turboed Cat (162") for fun. Might also take a stock 09 163'' for stock vs turbo compare
.
Since I have been working on the install and operating instructions I wanted to post the elevation/boost/fuel requirements I am recommending. We have deviated from these for our own testing purposes, but I will have to stick with these for the consumer. If you go outside of these recommendations--YOU ARE ON YOUR OWN!
These are recommendations for fuel requirments with fuel pressure @ an idle pressure of 3-5psi.
1500' 5-7 psi 91 or better pump and race fuel 50/50
7-9 psi 108+ MON race fuel 100%
9-10 psi 112+ MON race fuel 100%
At 1500' elevation we do not recommend any boost over 10psi.
3000' 5-7 psi 91 or better pump and race fuel 70/30
7-9 psi 91 or better pump and race fuel 50/50
9-10 psi 108+ MON race fuel 100%
10-12 psi 112+ MON race fuel 100%
6000' 5-7 psi 91 or better pump and race fuel 50/50
7-9 psi 91 or better pump and race fuel 70/30
9-10 psi 108+ MON race fuel 100%
10-12 psi 112+ MON race fuel 100%
8000' 5-7 psi 91 or better pump fuel 100%
7-9 psi 91 or better pump and race fuel 70/30
9-10 psi 91 or better pump and race fuel 50/50
10-12 psi 108+ MON race fuel 100%
10000' 5-7 psi 91 or better pump fuel 100%
7-9 psi 91 or better pump and race fuel 70/30
9-10 psi 91 or better pump and race fuel 50/50
10-12 psi 108+ MON race fuel 100%
12000' 5-7 psi 91 or better pump fuel 100%
7-9 psi 91 or better pump fuel 100%
9-10 psi 91 or better pump and race fuel 70/30
10-12 psi 91 or better pump and race fuel 50/50
I know it looks like a lot of numbers and there is no doubt some insurance built in for the fuel recommendations for my security. I think most people will probably find a low boost setting and a high boost setting and stick with that. One boost setting or one fuel is defenately the easiest way to go. Just don't let the chart scare you
. It really is easier than it looks. Bottom line is fuel is cheaper than a rebuild and if in doubt run higher octane fuel.
These kits were designed and tested to be sold for 10-12 psi of boost. Until people get used to that then they will start expierimenting on thier own and turn the boost up. I run over 15 psi on my personal sled on a diet of 114 fuel at 6000' and up.
Just some more info to consider.
