i wanna run about 15psi on myt h22a (8.8cr), what size injectors would i need and could the vafc hack control these larger injectors along with a 3bar map? also, about how much ;power would i make at this boost level? would i have any possible ignition problems while running race gas using the stock ignition?

sell the vafc and get hondata or aem ems , you cant run over 10-11 psi on the hack and i would not trust it on a h22 even at that psi, and you cant run a 3bar map with the hack

yes you can, do your research. You need to change two values i believe in its input output fields, people do it though uncommonly. You CAN run the H22 turbo off a VAFC but it would possibly be a stretch. You'd more or less need to use 440-450cc injectors for voltage reasons that will come into play against your ecu. The 3Bar might eliminate this somewhat, but i dont feel like buying a 3bar right now and testing it. Reallistically id say sell the VAFC and get hondata. Just get the basics of what you'll need to run, have it tuned, its gonna be safer in general. If you wann run the VAFC expect to spend a lot of time fine tuning your map on the road and to get peak power you may need a dyno. You'll also need a way to retard timing under boost or just set it at the distributor. Basically you have to learn a lot to do it as well with the VAFC as hondata will do it. It can be done though. Good luck!

what kinda power do u think 450's will support? u think i could run 15 psi using these and the vafc? about the timing thing, i'll only be runnin 15psi when racing, and using race fuel, and like 6-10 on street, using pump gas. i just wanna make sure i'm gettin enough fuel.

 

u have a built motor dont skimp out on engine management...get hondata if u can, if u are pressed for cash, get uberdata

 

like stated above...you spent all that $$$$ on your motor and you wanna cheap out on a/f managment?!? that's a no-no! but to answer some of your questions about running the hack...yes you can run a 3 bar with the hack and run up to 14.5 psi. i was one to do this...but with UberChip which retarded my timing to counter the advancing that the hack causes. do some researching if you wanna go this route just till you can afford hondata/aem/motec or whatever you wanna run. but whatever you do, good luck!

 

ok, thanks for the replies guys. about the injectors now, about how big should i go to support 15psi, and can the hack control them?can i also use an fmu to increase the fuel pressure if needed?

whats the most anyone has ever boosted with the hack?

 

ttt

 

If your looking for a vafc, here's one for a good price...

for 15lbs on a lude i'd go with 62 or 72lb injectors

 

would the vafc be able to control those?

 

Nope
