AverageVolvo Posted September 9, 2011 Report Share Posted September 9, 2011 Uploaded with ImageShack.us I personally would not go bigger than a Gt35r Not sure what the flow rate is. That is unless your engine is built to handle 8k+ rpms Link to comment Share on other sites More sharing options...
Texas850Turbo Posted September 9, 2011 Report Share Posted September 9, 2011 for any given engine and power curve, there is a turbo combination that matches it best. If the turbo is improperly matched (60 lb/min airflow if you only want 300hp, for example), then use something else. google borgwarner matchbot to match a turbo with help, or if you're baller you can get ahold of a set of maps and do the calculations for the match yourself.

Hoosier Daddy Posted September 14, 2011 Report Share Posted September 14, 2011 any ideas in regards to the VE of these engines? Link to comment Share on other sites More sharing options...
ozzimark Posted September 14, 2011 Report Share Posted September 14, 2011 Log RPM, MAF and MAP, do the appropriate math, and you got your VE. Of course, VE will change with a new turbo, but at least it gets you in the ballpark. If you don't feel like going through the effort, assume around 90-95% peak, dropping to 75% by redline for a stock setup. Link to comment Share on other sites More sharing options...
VolvoGuy500 Posted September 14, 2011 Report Share Posted September 14, 2011 I'm talking can flow 60lb/min It really depends what you've done to your head, intake path, and charge cooling setup. High-flow turbo? Sure, my Holset flows 87lb/min.. Will I ever get that kind of VE out of the motor? Never in a billion years. I'll be lucky to see 65 or 75. As others said - do out your VE and see what you wind up with. Unless you've got a ported RN head - 03 LPT is best from what I've heard, you'll never get anywhere near the flow you want.

ozzimark Posted September 14, 2011 Report Share Posted September 14, 2011 VE measured in lb/min? Port-wise, all the RN heads should be the same. Mid-01 to 02 saw a change from 7mm to 6mm valve stems. The only other important things that change are the cams and VVT Link to comment Share on other sites More sharing options...

Alan M Posted September 15, 2011 Report Share Posted September 15, 2011 I run a large KKK K27 Borg warner unit and calculated VE across a all the entire rev range and found the turbo to just be inside the ability of the engine I used. The later engines with higher lift cams can cope with a 70lb a minute turbo through practice I have found. By later engine I mean the 2005 on B5244T T5 variant engine. The head is a better shape with smaller valve stem. You will need very good boost control when running large turbos as I found when poorly matched actuators were fitted aginst the boost control used boost was inconsistant and very unstable at various rpm points.
