big-phil Posted August 1, 2008 Author Share Posted August 1, 2008 Phil, are you and Chris getting all that power from the 2.8L, or did you stroke both engines? Greg They are both stock stroke, mine is stock 86mm and Chris's is 88mm. I have cast pistons, Chris has forged. Quote Link to comment Share on other sites More sharing options...
Soundmasterg Posted August 2, 2008 Share Posted August 2, 2008 Ok, so stock stroke and a larger bore for Chris and forged pistons.... and you've got smaller bore and stock pistons...still making all that power and torque.....sounds like a plan. Here I was thinking that I'd need to find a diesel crank and get 3.1L to get the power you two are getting. I can just stick with the L28 crank then. Sweet! Thanks Phil! greg Quote Link to comment Share on other sites More sharing options...
ktm Posted August 2, 2008 Share Posted August 2, 2008 I am making Phil's numbers on a stock block, head and intake as well at 21 psi (plus 25% methanol replacing primary fuel). It is all about the tuning. As a matter of fact, I have a feeling I am up over 410 ft-lbs now after I found a small boost leak, fixed my boost bleed-off problem, added in some more timing (left 5+++ on the table), and retuned. It feels noticeably quicker, as in holy **** this thing is going to kill me! I hit 20 psi by 3300 rpm and hold it to redline now. The plan is to hit 22 psi and then add in some more boost past peak torque up to 25 psi by redline, or maybe just do 20 and up to 23 by redline. I am going to hit the dyno as soon as I resolve my clutch disengagement issue next week.....I hope or I am selling the damn thing! Quote Link to comment Share on other sites More sharing options...
