So i took a trip to the dyno shop i always do my pulls on and i am very please with the results. Truck produce 369rwhp/429rwtq (only 7lbs or boost) at an A/F of 11.4. These numbers were produced on my 35" tires and 20's...I apologize for the poor quality picture of the graph, i do not have a scanner. Let me add this is still not a custom tune rather it is the tune Magnacharger provides with there kit.

 

That's with the new (2.7) upper pulley? How much of an increase since last dyno run?

 

weak

 

yes that is with the 2.7 pulley, but in theory going from a 2.8 to 2.7 will not gain that much.. I think allot had to do with the new intake i had setup for the truck, because when i had gotten in there my WOT a/f was in the 13's..



old dyno was 350/390 compared to the new 369/429 wil probably be going for a custom tune here in the next few weeks if all works out to plan. Boost level is still 7lbs btw...

 

pump up the boost and custom tune. Lets see it put down 400+

 

I am actually a little afraid now being that im on 35's and those have to be taking at least 30rwhp or so.. so don't want to break that safe zone lol..

For me to up the boost i will need a custom lower to overdrive the system.. anything smaller wont fit on the upper and will just slip like crazy..

However, first thing on my to do list is plugs, seems like the truck was getting a lil spark blow out..

 

Cool, hopefully I can get to the dyno in about two weeks myself. I want to see how my numbers are with the headers and blower port I had done back in spring. I will try to see if the shop will let me switch out the intakes (stock vs mine) in between runs to see which one performs better. This of course all depends if wife and kids and in-laws don't have some unexpected detour waiting for me when I finally get a time setup.

 

JDM sells lowers.. I never asked jim how much they where though.

 

I contacted them about a week ago, they said they do not have any in stock or plan to get any soon. Also spoke to innovators west but they are giving me the run around.

Before heading to the dyno id get that belt slip issue resolved. Truck wont make any power if you cant get it to produce boost from slipping.
I don't know about those long tubes.. i lost some power when i had those on my truck... Good ole stock manifolds seem to be working for me lol..

i am interested to see if that port helped any.. i know it is suppose to lower charge temps, but how much IDK...

 

I thought I guestimated 370/4xx when you asked, so I was close! Lean out AFR a little and make some more power.

 

did you just up the WOT % of fuel with the tuner and thats it? Pretty sweet #'s, my pulley is not on yet, I really don't want to run it like that without dynotune
nice tho.

 

no other tuning other then added fuel via the x2, just like you said added WOT fuel %..

what pulley did you get?

 

2.7"

 

From what company?

 

pulley boys
