Who's in for a BEGi Down Pipe?
#23
I never said BEGI's DP wouldnt be a good idea...and bigger is always better as they say. But again, the major restriction in the Greddy system or any turbo system for that matter is the turbine itself. My GT32 has an outlet of 2.5in. I have a 2.5in custom DP...I might have used a 3" but I couldnt fit it plus the gains really are minimal. I understand why you say larger than 2.5" will make power...because you still have exhaust volume to think about...and the larger the pipe the easier it is for the exhaust to make its way out. But still....2.75" -vs- 2.5" is not going to be night and day. I would expect 100rpm gains in spool and MAYBE 5whp mostly from the better WG merge of the BEGI DP. Im just stating my opinion...and I have nothing to back it up with either. Just using general physics and knowing that the biggest restriction is the turbine wheel and 2" outlet you can deduce that the gains from a larger DP will be very small.

Well, it's up to BRG now. If he gets his car in next week, Corky and Tim will mock it up.
It would be bitchin if BEGi throws BRG's whip on the dyno before and after. If it ~only~ gives 5 hp more than Tony's it's worth the minimal extra investment.
