Cost will add up more but it's an option that works well. Link to comment Share on other sites More sharing options...

You actual read my mind Ive been setting up my ecu to control some spray on my car for when my 3788r maxes out flow haha. My plan is to see if I can get my stock bottom end sohc to make 750+hp without putting rods on the floor. Link to comment Share on other sites More sharing options...

Not ruling it out tho! 1 Link to comment Share on other sites More sharing options...
eff xr6t Member 569 Member For: 11y 1m 30d Posted 09/03/16 06:03 AM Share Posted 09/03/16 06:03 AM Wet shot would be required in your case because you won't have the ability to add fuel with the stock ecu when the gas comes on. Would probably need a second tune that you put in just when you have the bottle on to pull the required timing out of it. I'll be keeping my AFR the same 12.0 with the gas and then just pulling a couple of degrees of timing till its happy. A few of my mates are playing with it ATM to get there cars to come on boost quicker because rb30 and 2jz lag machine with gtx47 size turbo they just use there ecu (haltech) to spray when the parameters are met rpm, tps and map. Logging it says it only sprays for 1second which means there bottle last years. Link to comment Share on other sites More sharing options...

Edit I spose the same could apply to timing come to think of it. 1 Link to comment Share on other sites More sharing options...

Does that not block exhaust gases in the manifold from 3 cylinders? That cant be a good thing? Link to comment Share on other sites More sharing options...

Isnt that picture of the quick spool valve showing the valve across one scroll? Or is there a T3 version? I cant see how it would work on a single scroll housing. Wouldnt it just cause engine backpressure and heat, and limit turbine flow and cause more lag? Link to comment Share on other sites More sharing options...
