datsunlover Posted July 3, 2005 Share Posted July 3, 2005 Actually, I'll bet the 220 mark would be attainable.. I've heard of some people taking serious amounts of material off the head.. (like .060"!) the p90 (turbo) is the best flowing head as far as I know. . Then some good working of the head and a nice cam, combined with flat top pistons and say triple carbs.. you'd be making some good power, but it'd be expencive and a little hard to stay 'streetable' I would think..

Clifton Posted July 4, 2005 Share Posted July 4, 2005 Ya it's possible but not with stock bore SU's. A BIG cam and alot of head work so the head can flow at higher RPM. Forget low rpm torque and shifting at 6k. Quote Link to comment Share on other sites More sharing options...
Silent Posted July 4, 2005 Share Posted July 4, 2005 laff. i made 192 with stock su's. aside from the sm needles. on a stock n47 head. if you know what you're doing with the carbs, and the engine itseld it can be done. it has been done. and it has been done on su's mines a 3.1, hence the higher then normal numbers. and a puny cam, with a crappy tune. su's have been recorded as high as 270 rwhp.not stock ones though.

Tony D Posted July 4, 2005 Share Posted July 4, 2005 What would Norm's car have to have to run that 12.80 Sec 1/4 mile at 107mph? I mean, that's with stock bored SU's... And pistons he "milled" using sandpaper on his driveway... Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted July 4, 2005 Share Posted July 4, 2005 220rwhp is pretty up there for a 100% stock block (read: non bored/stroked)motor. Don't think I've heard anyone getting that high on stock block and SU's, but some really good head work and cam might just do it or get you really close. I think the max I've heard of on a stock 2.8 is around 200rwhp. I had an overbored 2.8 which was technically a 2.9, but not stroked, some mild head work, medium cam, and SU's, and put down 170rwhp. I would have expected another 20-30 from some 'real' headwork. Quote Link to comment Share on other sites More sharing options...
