Crouch Posted May 21, 2011 Share Posted May 21, 2011 Well its time for me to post one of those threads that everybody hates as it's been gone over fifty million times but i have to ask as the turbo i'm considering isn't found much on the search function. The question is this... the turbo i'm thinking of is the GT4202r but the thing is on the fullrace site it states this is rated at 1020hp but is this fly or wheel hp? would this be the rating at 2bar+ boost levels with race fuel or nitrous? Will the fact that i'm going to run a 3.4ltr stroker effect the power out put of the turbo? it should help the turbo spool but does it effect actual power as in two engine identical spec in all ways but one strokerd would they get different top line figures? Sorry for the daft question but lets face it the turbo makes such a difference in the way the car behaves i want to make sure i have as much info as i can get for an informed choice. Any input welcome. Gary Crouch Quote Link to comment Share on other sites More sharing options...
Crouch Posted May 23, 2011 Author Share Posted May 23, 2011 Nobody had one of these turbos then? I'm sure Mr Whifin said it was a good turbo but what others would be recomended in the same 1000hp bracket? Feel free to chime in at any time honestly anybody its something i need to know before i buy a fullrace kit and find it's cack!! Quote Link to comment Share on other sites More sharing options...
aman00123 Posted May 23, 2011 Share Posted May 23, 2011 Well I'm not an expert but would assume that a stroker kit would result in top end bhp increasing due to the increased displacement? And the quoted figures for the turbo will be on a big engine at full whack with race fuel etc etc As for turbo choice it would seem pretty good, but why not go for one of the new "Batmowheel" ones - seem to put some good figures out, smaller turbo but more power, been shown on more than one car aswell Also it would be good to know what you're going for and the rest of your spec - just because I'm nosy Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted May 23, 2011 Share Posted May 23, 2011 The horsepower rating is for the engine, it doesn't take transmission losses into account. Quote Link to comment Share on other sites More sharing options...

Crouch Posted May 23, 2011 Author Share Posted May 23, 2011 Also it would be good to know what you're going for and the rest of your spec - just because I'm nosy To be honest mate i've just started so not much to tell yet just putting an engine together on the side untill i can get the diff/prop and driveshaft to take the power. so far i've only got Hypertune plenum,corbonetic twin plate clutch,billit main caps,carillo H beam rods,just sorting the custom pistons and crank with Mr Lee p at the moment. i was planning on a fullrace turbo kit next week or two but seems theres others to check first! fastest spooling 1000whp turbo out there is the Precision billet GT42-76r from what ive seen, go full divided setup is my advice. is this not what you use Mr jamieP? do you rate the fullrace manifolds or would you say theres better out there as they are devided i believe.
