Default Good.21 for under $300.00

Sorry for posting a "noob" type of question but the wife has me on a super tight racing budget and I need some real world experience.
I run a rc8 on a small tight track. I have been running a Dynamite .21xp but it has zero low end punch. I have messed with clutch springs/shoes/pipes ect. It has killer top end, but not the punch I need for this track.

I have been looking at the vz-b and the Jammin.21JPX but I cant afford to
make another incorrect purchase.
I own a jp1 and rb mid range pipe (forget part # at the moment) and have access to a jp2 for the rest of the season.
Thanks for any help/ insight.
Jd

i would get the vspec, it has very good low end power and is good on fuel economy, i have heard of people having good luck with the jammin engines and bad luck as well, i personally like the speeds, but they are in the 400 dollar range

I had a few V-Specs and had good luck with them. I just wished they lasted a little longer though. I switched to the Novarossi P5XS ($279) and like that as much or better than the V-Spec. Much smoother power delivery for me. I haven't had it long enough yet to see if it will out last the V-Specs though. If they don't, I will go back to the V-Spec.

If you have a 300.00 budget a vspec can be worked in. Go to amainhobbies and with there discount coupons you should be able to easily get a new v-spec on your budget. It is a great motor. Good bottom, excellent fuel mileage, and still fast on the straight away.

How long ( gallons) are you all getting from the v-zb? What is a good pipe for it?
I had good luck with the os.12's in my gt2,so I figure the vz-b .21 should be just as good.
Was looking at the p5 rossi as well. Still might go with rossi if I can't find a vz-b at a good price.

Thanks

I ran a strong and reliable 8 gallons out of my last vspec. I do know a few people who have went longer though.

That's not bad at all. I was thinking they were only going a few gallons before they lost pinch/bearings. Sounds like a winner to me.
Thanks

most people get between 5-10 gallons, on a engine depending on how well you tune and break it in, you could use the jp2 pipe on it, i personally like the associated/thunder tiger 2035 pipe and manifold, you can get them for around 50.00 shipped with manifold

Do yourself a favor if you do decide to go with the spec get a set of tko bearings for it

V-specs are a great engine for 3 gallons and the that's it, blocks break, bearings go, and pinch is gone.

Novarossi P5XS would be my vote. Good all around power and a decent run time. Best part is the quality parts and reliability you get from being a Novarossi.

i used to be a novarossi guy, just had some bad luck with the last few that i owned, but it can happen with any brand of engine, just stay away from the cheap stuff like go-tech and sts, the most bottom end and top end power for your budget is gonna be the vspec, the rb concepts arent gonna give the kind of power till you get into a c6bb, i have heard the sirio engines and picco engines offer alot of performance for the buck, havent tried one yet, i have been running grp tuned and os speed both have held up really well
