JamieP Posted July 28, 2008 Share Posted July 28, 2008 Jamie, your old 4088 and vvteye's 4088R may need different hotsides to achieve the same goal For starters are they both divided or undivided? What about the manifolds? I dont think the .81 or .95 come in divided but may be wrong, either way a smaller hotside will make it spool quicker, just for reference i had a divided manifold with undivided turbo.

vvteye Posted July 28, 2008 Share Posted July 28, 2008 (edited) Maybe I'll get some piccies if it helps and we can move to a new thread I'll also check with Interpro who put it all together. Thanks for the advice though chaps, especially the links Jamie ... I'm hooked Edited July 28, 2008 by vvteye (see edit history) Quote Link to comment Share on other sites More sharing options...
Alex Posted July 28, 2008 Share Posted July 28, 2008 The "ideal" other than the holy grail of instant boost from idle to the red line is a turbo that gives great lowdown shove and keep up the thrust to 0-500rpm of the red line. If a turbo is still getting into it's stride at the redline then really it's too big. Changing the hotside will move the powerband up or down the revs and with either maths or trial and error you'll find a hot side that gives you as broad a powerband as possible. This adjustment up or down will change the fuel and ignition requirements throughout the new powerband. Hence the remap. Quote Link to comment Share on other sites More sharing options...

OK, for the sake of research, the car is going to Ryan LAte Spetember and we'll check the dyno, then I'll tke it back and get the housing changed and remapped, then dyno again. hmmm... just working on an excuse now for the missus Quote Link to comment Share on other sites More sharing options...
Alex Posted July 28, 2008 Share Posted July 28, 2008 If it all went well Ryan could do both hot sides and preduce you two maps that you could load and run at your discretion. Quote Link to comment Share on other sites More sharing options...
