30lbs maybe more than the t-61 can sustain.i dont race this car,its just a street toythat tows my m/cycle to the track.....chip is of course burned for this combo and eric made timing default 19/18..which i bumped to 21/18*. For better or worse ,i tune from KR..which i had seen too much of just before pushing out left side h/gskt.i studed the heads this time, added felpros and am more careful with the alky tune.i know a w/band is the deal and and i need one for sure... o/2s now are in the high 700s when i blast it. ..scanmaster only. i,d like to be able to push timing past 21* which is wher it is know,and run boost up from 25 to maybe 28?. I have knock down to less than 1*.my alky tune comes on at 8lbs and ramps up pretty fast...this is where i broke it last time ..transitioning...gain is at 9. so ..it seems the stock alky kit is maxed. would a larger nozzle or maybe dual feed be the way to go,and if the turbo is at its limit at 28..maybe sneak timing up slowly and check for knock?(of course). after a "razor" and "eric TT guy"search it seems to me, knock, and when it appears, is the bottom line..a data log,wide band and egt is the ticket and i know this from tuning my turbo ,alcohol bike into the mid 7s..i am no stanger to this...just want to to explore what youall have found/do as well. thanks very much.
