| Re: The "4.9 liter turbocharger, stage 1" thread.
Illumina first we need to find a way to regualt the boost in stages , we dont really need 6 psi all the time ....so perhaps once we get the ECU stuff worked out we can then find a way to do a varible boost controll , i figured out a way to do this with that B&M shift improver i have laying around .....Might get the transaxel to live alot longer if we arent lopeing along on boost all the time ....
For intercooling i acutally half arse mounted one of my 1993 300ZX Twin Turbo Intercoolers i have laying around , its pretty small but good enough i think for a single turbo running that low boost of 6 psi. Fits the car pretty well , im thinking a electric fan from one fo those Tranny Cooler kits would fit nicely on it and keep air moving over the intercooler so i can mount it on an angle so at the strip i can set a bag of ice on it ....
I think RB is talking about a blow off valve ...only needed dureing shifts at high boost , keeps it from going into a overboost situation int he time between shifts ....we need to check what the GNX guys run , there turbocharged and automatic trannys. May not really need a blow off valve running the low boost and automatic tranny.
I acutally think wheelspin may be a saving grace illumina , that will keep us out of the intial heavy ammount of torque that kills these engines. Ive seen what they will do to these trannys now when a very high "kick" hits them , the trick will be to slowly feed it boost off the line ....Feeding 300lb ft off a dead stop is going to be alot harder on it then starting it off with a close to stock torque figure out fo the hole....so either a nice ammount of lag or wheel spin shuld keep these trannys alive...basicly try to maintain stock 60 footers , make up the diffrence down track...
sorry i was out for the weekend , got a little angry and decided i needed a internet break |
