I had a Wasp .26 and .28 and it made a world of difference, if you don't like what others say about the wasp go with the SH.28 regular 3 port not the PRO and you won't be disappointed either. They run at about 130 shipped off of ebay so it won't break the bank either. My savy ran the SH and it would flat scoot and my MGT with either wasp would too, and I am sure had I put the SH in it would have done great too. But any of those are good budget engines that will get the job done for you without alot of $$$. The wasp .28 will most likely keep you with your friends savage assuming he don't have a 3 speed in it as well, even so the W.28 will get you there in a drag. If he starts to catch you then just yell "now back" and make a quick turn back and watch his go into a roll and take your time coming back and enjoy the victory. lol I hope this helps you.
