Well i got my new gauge in and put it in and my idle psi is 44-45 but on the stand and reving it drops to 38-39 the first gauge read 42-43 idle pressure and it also droped to 38 psi now what do i do??????? :banghead:

 

[dead1dave]

disconnect it and forget about it . it's always done that .

 

[Firecat F7 Nut]

could that be cause its hot out?

 

[dr f7]

Is there any adjustment to it ? Thats wide open! Is it Safe?

 

[Firecat F7 Nut]

i dont think there is any adjustment to it. safe?? i dont know . WOT on the stand my EGT temps are only 1000 to 1100? i also have the BMP stock pipe mod, PAC, and D&D y-pipe. i think 1250 is the temp you dont want to reach. BA BOOM!! :banghead:
also have the same reading you do on the gauge 42 to 43 at idle and 38 at WOT.

egt is usless on the stand, you cannot do anything correctly unless the engine is under load

 

[Firecat F7 Nut]

i know that but how much can it change under load??

 

[dr f7]

f7 nut did you take your restrictor out or is it still in?

 

[Firecat F7 Nut]

it is still in. i am sappose to being runing my sled in the colebrook grass drags this weekend if i get my secondary clutch back from D&D by friday. if i run it i will let you know what i see for temps.

I am heading up to the outdoor shop in a couple of weeks to do some you know ... stuff

 

[Firecat F7 Nut]

ohh like what?? spend some more money? or do some tuning with dan?

 

[dr f7]

ahh yaayepp!!!!!! New track 1" hacksaw clutch tuning and 06 sheaves! but im not sure about the fuel restrictor im a little uneasy about it what good will it be if i can never turn it down Im going to have to see when the snow flys if its diff i dont have the pipe mod yet ! but doing it soon!

 

[Firecat F7 Nut]

i want to get the new hacksaw 1 in track. but i love the sno pro track!! same here if i feel to uneasy with the PAC i am just going to take it out. i am going to try the D&D clutch mod instead of the new sheaves. do you go up to rangely lake at all??

 

[dr f7]

no but i was just talking to a buddy of mine and we may try it this year i go to barre vt.

 

[dr f7]

im going to chat !!!

 

[firepower flyer]

That sucks I bought the same setup,I hope all the gauges are not off. :frech32:

 

[cmscat50]

You have to test the restrictor anyways on WOT runs.

So why not just take it to the lake (when we get ice) and start off with a short WOT pull and check plugs. If ok run longer and longer until you are comfortable with the plug reading. If it's lean take the restrictor completly off. If it's rich you can adjust down on the lake.

Not sure why you are nervous here. Do the testing first. Take 10 minutes max.

WELL THE ONLY THING IM GOING BY IS THE STAND A REV IT UP A LITTLE TO ENGAGEMENT THEN BLIP IT AND HOLD A SECOND OR TWO SPEEDO READING 122-124 THEN BACK OFF TILL I SEE WHERE THE GAUGE IS DROPING TO WHICH IS 38 PSI IS THIS NOT AT ALL ACCURATE?

 

[87gtNOS]

LOL!! this is funny, I laugh everytime someone asks what FP to run on their F7!! No two guages or sleds are alike. Different quality guages will have different readings!
I have on my car an electrical and mechanical guage on the fuel rail. They are both tee'd on the same spot. The electrical guage (in the car) reads different.
All in all, it's for your own reference.

btw..FP at idle is fine..but you aren't getting anything on the stand....you need to drive the sled to create load and then you will see the proper reading.
