It looks like it will either be a KB 2.8lc or a whipple 2.9l. Problem is, that I cant find any hard data comparing the two. It looks like the KB has a more advanced screw design and some better cooling features, but on most forums people state the whipple has lower AITs. What do you guys think?

If you can't find hard data, maybe you could find enough slip data from people with otherwise identical setups to use trap speeds as a proxy. That's not great either and my guess would be that any difference you could find would not be statistically significant, but you never know. You could also pull the old calling their sales line and just tell them ,"it's between your model (a) and their model model (b), why should I buy yours?" If they have a technical applications specialist they should be able to spout off any hard differences. If you hear only spin, then the differences are probably moot. In that case, just go with the better deal you can find since it would be kind of a commodity question at that point. That's how I'd approach anyway.
