davej705 Posted November 26, 2010 Share Posted November 26, 2010 I think the kit you have is fine mate,if you get lag change gear Quote Link to comment Share on other sites More sharing options...
Bailey. Posted November 26, 2010 Author Share Posted November 26, 2010 i dunno what i am worried about, as said, once your flat out your not dropping out of boost when changing gear. add has put me straight today, so i say i will give it a go, and then in the future near or not, go for a whifbitz s366 kit, no more talk, i just want to get started now, paul get those dang pullies finished, lol Quote Link to comment Share on other sites More sharing options...
Bailey. Posted November 26, 2010 Author Share Posted November 26, 2010 7500rpm really think for another 250 rpm its a bit ott, a worthy addition with a built bottom end though! Quote Link to comment Share on other sites More sharing options...
dude Posted November 26, 2010 Share Posted November 26, 2010 really think for another 250 rpm its a bit ott, a worthy addition with a built bottom end though! You can prob push it a bit further but at what cost, BTW you should really be changing at 6750 and unless you have cams you will be losing power way before then.

Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 With dual valve springs and ARP rod bolts, you can safely take it to 8000 RPM. I've yet to see a motor with the above mentioned, fail due to revving 8K. Quote Link to comment Share on other sites More sharing options...

Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 As a matter of fact I have, with heavy abuse I might add. Actually 8400 RPM. Quote Link to comment Share on other sites More sharing options...
Bailey. Posted November 26, 2010 Author Share Posted November 26, 2010 what miles has your engine done? previous and since? and whats your setup! Quote Link to comment Share on other sites More sharing options...
davej705 Posted November 26, 2010 Share Posted November 26, 2010 I have a fully built head and having a fully built bottom end and am going to limit revs to 8250. 8400 seems high for bolts and springs It's all irrelevant anyway mate,as dude said you'll be changing gear before the limit anyway Quote Link to comment Share on other sites More sharing options...
Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 I'm on a stroker now with a redline north of 9K, but my old setup was a stock bottom end with rod bolts and a built head (dual springs). The motor had around 85.000 KM on it before the bolts and head. An unknown amount of those KM was on a big single. Quote Link to comment Share on other sites More sharing options...

Bailey. Posted November 26, 2010 Author Share Posted November 26, 2010 and for how long did it last at those revs? Quote Link to comment Share on other sites More sharing options...
Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 I agree that 8400 is in the high end, which is why I suggested 8000. Quote Link to comment Share on other sites More sharing options...

Sounds cool.start a thread because in doing a stroker build and It will be cool to get some tips Quote Link to comment Share on other sites More sharing options...
Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 The old engine is still running strong in the new owners car. I think it's running a T04Z now. It has more than 120.000 KM on it by now. Quote Link to comment Share on other sites More sharing options...
davej705 Posted November 26, 2010 Share Posted November 26, 2010 that extra bit of power band would be nice though mate, but i would like my rods on the inside of my engine if possible, lol When the power drops off change gear for maximum acceleration mate.revving the engine past that point doesn't really make sense to me! You could change cams of course... Quote Link to comment Share on other sites More sharing options...
Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 There is quite a few of such threads to be found on the US board Quote Link to comment Share on other sites More sharing options...
dude Posted November 26, 2010 Share Posted November 26, 2010 No need to do a thread dude, most of the stroker kits say they are fine to those revs, the Crower says 9500rpm , mine is apparently 10,000, guess we will find out next year.

Swampy442 Posted November 26, 2010 Share Posted November 26, 2010 Glad you saw sense and are thinking about ditching the 88, its a diplodicus compared the the raptors of modern turbos Quote Link to comment Share on other sites More sharing options...
Guest JDM_DK Posted November 26, 2010 Share Posted November 26, 2010 Agree, But running a fairly large frame turbo that will sustain a positive boost/BP ratio past 7500 RPM, and NOT having cams to support it, that is pointless IMO. Inefficient in terms of power band. Quote Link to comment Share on other sites More sharing options...
