Boost Gauge, Cummins Conversion, Rolling in & out of the throttle.

thats weird i have a sps 66/71/14 and it starts lighting at 1650 1800 rpm and i only have 90 sticks make sure you have a good tranny and put the torque management all the way at 4 and u will like it a lot more also bring those psi up i have mine at 50 but capable of 60plus just waiting on my hamilton 110lbs springs to get in

Check out the vid turbo boost vs back pressure.

[austinshirleylilbo76]

listen to tha cummins whistle

[06cummins92]

What size turbo are you running on it if it's no lighting till 2k

[jtharvey999]

64/71/13 stainless from HTT.  Trying to figure out something different right now...it's too laggy and runs hot.

[06cummins92]

I'm runnin a 66/14 custom built with a titanium impeller on my 97 cummins and it will light around 1500 but like you said mine is pretty laggy until then too.....mine stays around 1100* behind the turbo with a heavy load and stayin on the pedal so i can't complain

[hsvkidusa]

absolutely not flooring it lol

great video! single right? youre able to keep some pristine control over that if its a twin

[jtharvey999]

Yes, just a single for now. Looking into a compound setup though.

[schoenauerd]

ha ha ha, my 1996 12 valve cummins gets 40 pounds of boost with one turbo on it

[jtharvey999]

ha ha...this CR will hit well over what's in this vid, with only one turbo on it. The vid is no where near WOT, maybe 1/2 to 3/4 throttle. That's why the title says, rolling in and out, not hammer down & WFO.

[jameson1333]

@schoenauerd yeah, you're probably one good throttle punch away from blowing it up too. It's not about the psi it's about the volume of air the turbo moves

[blondeguy08]

what rpm be4 ur turbo begins to spool

[jtharvey999]

It lights pretty hard right around 2000 RPM.
