Hey all where do you all run your mp-8's at 0-100? just taking a poll.


Thanks

40%!!!!!!!!!!!!!

With stock injectors you should never exceed 50%. Now that I have some Fluxs I run it 50-60% most of the time but occasionally turn it higher.
Like last night.
I was sitting at a light and another CTD turned onto the road I was on and eyeballed me as he let the black cloud billow from his 6" stacks. I got skeered and flipped it to 4x4 and turned the Juice to HOT and the mp-8 on 100%. Pulled up to the next light and it was on. Let's just say I could have left the mp8 off and the Juice on 4. I always feel bad when I whoop up on a fellow CTD owner.

Now you should be doing that!!!! LOL....

I run mine @ 40-50% daily and at the track i turn it up all the way!!

Sorry for a dumb question, but how exactly does increasing the fuel pressure give you so much more horsepower? As I understand it, the MP8 is just a pressure box.

MikeyB

Because more fuel is being delivered with the same amount of duration from the higher pressure. Also there's a slight timing advance that comes from the higher pressure when the injector fires.

Thanks for the answer. Given more fuel is delivered at the same duration, do pressure boxes make fuel economy much worse under the same driving conditions?

MikeyB

Really depends. I ran a Edge EZ pressure box at level 2 (50hp) and saw a slight decrease in fuel economy for city driving, and no change on the highway.

Cool. Thanks for the info...

thanks for the info. Does anyone tow with mp-8 and what would you set it at or what have you set it at while towing and had good experience with it.

I run mine on 40-50% all the time. After hearing some of the posts here i contacted T/S Tech , and they told me 0-100% would not matter. Also said no injector problems have been reported. So, if there is any issues with running it at a higher % , they should be contacted.

yoda76

bish1, I'm assuming you still have the stock injectors?

i run mine 100% most of the time for about 20,000 now with no problems the boys at Ts performance told me 100% wont hurt it at all.

How is running it 100% any worse than stacking it with a smarty or somthin and runnin them both 50% ?????

Hintz

b/c the smarty doesnt add pressure
