wouldn't really be able to give an esimate, but with the proper tuning I'm sure you could expect a major difference. I mean no one who goes twins ever does try to make them really lag less because it defeats the purpose of the high end dyno queen twin setup.

basically I have my notes somewhere but the 2540R's get like 640-680 on a minorly tuned mkiv. so that;s enough power with a lower spool then a single that gets equal power with more room to grow. I was told that a custom 2450R kit with proper tuning and the right stuff could out do any single on the street in the same range.. I dunno what that meant but I'm sure it could spool and power with the best of them.. I'm just waiting til either somone roles with my research or I get the proper funding and knowledge to do it on my own mkiv..

Thanks
for the reply. How rpm's do you think they will spool sooner.
