We are having to replace O-rings for our molds during every service to prevent failure from O-ring compression set. We currently use 100 series Viton O-rings encapsulated in a .073" deep bore, for our static seal waterlines. General mold temps are around 320-350F. Each mold currently has...
I just solved what I thought was (is) a concern when trying to tune individual throttle body setups with only a MAP / Speed Density ECU with no alpha N. ITBs setups have notoriously been difficult to tune this way due to very low vacuum levels at idle and above. This greatly reduces the...
I know that some drag teams run fuel coolers to cool their fuel to sub ambient temps prior to runs and get a HP gain out of this. I am building an all-out effort turbo 4-cyl.
My questions are these:
What is the average temperature increase on fuel in an EFI engine running around...
I am designing a individual throttle body and using double sealed bearings for the shafts. I must be able to seal +35psi and 30in vac through the bearing. I just don't have much experience with bearings and cannot find an answer on this anywhere.
Is this possible with just a double sealed...
Theory:
In turbocharged application, a blow off valve (BOV) can effectviely be replaced by a 2nd throttle body that is placed right in front of the turbo compressor inlet.
Why it works:
All turbo charged systems need some way of elminating compressor surge upon the throttle being closed...
I am in the process of designing/fitting a set of roller barrel ITBs (Individual Throttle Bodies) to my Subaru STI and was looking for some insight on some things. This is something that is underway and going to happen so please don't try to talk me out of it, or say it won't make any HP, etc...
