Bailey. Posted December 29, 2010 Share Posted December 29, 2010 looking good, does it feel laggy when on normal roads with day 2 day driving? Quote Link to comment Share on other sites More sharing options...
Scott Posted December 29, 2010 Share Posted December 29, 2010 Looks very laggy, what turbo is it? Quote Link to comment Share on other sites More sharing options...
JamieP Posted December 29, 2010 Share Posted December 29, 2010 Looks very laggy for a 68mm turbo, 5100rpm you are making 340bhp, my 76mm turbo is making about 750bhp at the same revs, same dyno. Quote Link to comment Share on other sites More sharing options...
pauld36 Posted December 29, 2010 Author Share Posted December 29, 2010 havnt been able to run it on road yet due to weather but obviously i understand what lag is but how would you reduce it Quote Link to comment Share on other sites More sharing options...
Bailey. Posted December 29, 2010 Share Posted December 29, 2010 change down A gear is the cheapest way... Quote Link to comment Share on other sites More sharing options...
JamieP Posted December 29, 2010 Share Posted December 29, 2010 havnt been able to run it on road yet due to weather but obviously i understand what lag is but how would you reduce it Hard to say, could be anything, turbo looks huge for 68mm, i dont know the other specs of it, maybe thats what them turbos spool like, all the same with 700bhp it will still be hugely fast, dont worry about the lag, drive and enjoy i say.

pauld36 Posted December 29, 2010 Author Share Posted December 29, 2010 i blew mine up and bought it from paul at whifbitz it was his personal one that he never got round to fitting ,he said that it was borg warner internals but as you say it is very big for 68mm,but ryan reckons that once i change injectors the engine and turbo should be good for 900 horses,however if im gonna suffer huge lag then massive surge in power it is never gonna be controlable,i would far rather have a smoother delivery of power cos at least then it will be useable,any thoughts Quote Link to comment Share on other sites More sharing options...
Scott Posted December 29, 2010 Share Posted December 29, 2010 What pressure are you running at? It might just be a huge AR exhaust causing the lag. Are you aiming for 900hp? If not then I would sell the turbo and aim for something with a little less cushion Quote Link to comment Share on other sites More sharing options...
JamieP Posted December 29, 2010 Share Posted December 29, 2010 I think it will be ok, if you want big power there will always be a trade off for spool, ive never much liked the borg warner turbos myself as ive not seen great results from them anywhere yet when compared to the latest billet dbb precision units.

pauld36 Posted December 29, 2010 Author Share Posted December 29, 2010 unfortunately i dont know anything about turbo quality so i was in the hands of someone else,selling not an option as its all brand new an just fitted, Quote Link to comment Share on other sites More sharing options...
pauld36 Posted December 30, 2010 Author Share Posted December 30, 2010 i am only running about 1.4 bar of boost would that make any difference Quote Link to comment Share on other sites More sharing options...
JamieP Posted December 30, 2010 Share Posted December 30, 2010 Spool time will be the same with more boost, it will just ramp up quicker, be interesting to see what power it does at more boost, i have a feeling it will make huge power.

pauld36 Posted December 30, 2010 Author Share Posted December 30, 2010 everything in engine ready for more power but got to get some 1000cc injectors ,that should be all i need[famous last words ] Quote Link to comment Share on other sites More sharing options...
JamieP Posted December 30, 2010 Share Posted December 30, 2010 If you want 900bhp i would go bigger than 1000cc injectors, they will be maxed out and not good for flow. Quote Link to comment Share on other sites More sharing options...
