mass air question

[S+@ng]

i posted this on corral but nobody seems to want to reply so maybe some of you guys will know the answer.

I'm getting a kenne bell 2.6 and have tried to contact KB several times and no response in 5 days, i heard their customer service sucked and now i believe it. Anyway, i was reading on their site that the stock mass air is pegged at 400hp, and a 90mm is pegged at 475, so they suggest getting a 100/125mm after 475hp. yet on their own test car they made 682 with a 90mm?! i dont get it, maybe im retarded. They also had 60# injectors which i intend to use also. Heres the link for the complete story in case i missed something. thanks guys.

Lol you are retarded. Just kidding. U can use a 90mm maf with a extender like the diablo check that out. It should work.

[Killercanary]

Depending on how much power you plan to make, you may want to check out ford racings new 80lb/hr injectors. When I finally get around to putting my turbo on I will running these.

As for your MAF, I'm sorry but I can't help you.

roger that fresh, ill look into it. you better be right or i might have to kill you. hahah

80lb? dam, my buddy just got his 05 back with
76mm turbo (i think thats what size it is) and hes putting low 600's to the wheels with 62lb/hr injectors and kenne bell BAP but its his fuel pump thats running out so i think hes going dual focus SVT pumps.

60's will be fine and I run a 95mm Velocity meter from PMAS and that will also be plenyty for you

hmmm thanks, ill definitely consider that. ive also heard people using the SCT2800 which claims to be able to handle 825hp and not peg.

i think you'll be fine with a 90mm mass air

thats even what the KB test car ran and they made 682hp (give or take a few) but for some odd reason they suggest a 100/125mm meter which is what i dont get.

yeah i dunno...maybe so you have some room to grow

if you planning on sct tuning I'd go with a sct meter.They are a very good meter

na not really plannin on SCT ill most likely end up with that PMAS although im still open to suggestions. Ill probably end up taking it to a guy in panama city who did my buddies turbo '05 to get it tuned.

hmm this seems to be the end of my searching. excellent call! thanks

No Problem..

Are you going to have someone do a real tune on this for you? Why I ask, look into the PMAS slot type sensor. If it gets close to pegging, just put it in a bigger pipe :D My set up with a 3" tube is good to 550 hp, going to a 3 1/2 tube goes out past 650. You et an excel file with the meter that you enter the pipe size and it gives you the MAF curve. The issue is, it needs entered to the EEC, not that MAF / Injector crap everyone tries.

yea, im going to have someone else tune it for me. the PMAS says its good to 1000hp, but doesnt mention anything about the size of the pipe. FWIW i'd probably be using the KB 4" or 5" cold air kit and im hopin to get close to the KB test car #'s (682hp)

[Martin0660]

We will see if this works. 4" pipe is good for 1144 hp :D You have ot enter the REAL inside diameter of the pipe, but you get the point.

On Edit - That pasted ugly from excel, but you can see the point. This shows you how sensitive it is to tube diameter changes. A real diameter of 3.8 (probably close for a 4" od tube) cuts it to 1000 HP range.

There is another part of the HPX tool that lets you enter the calculated area of the tube, that's more acurate IMO as the diameter tool rounds to the tenth, the area takes three decimal places. In my application, it seems like it's pretty close to calcumated lbs/minute flow. We will see when I can actually get the car on a dyno and log both.

[S+@ng]

hahaha, yea 1144 is PLENTY for me:awsome: thanks for postin the numbers too it may prove to be very useful in the near future
