Default Whats the deal, for real...

Ok, I know I might be opening a can o worms on this one, and have done some research and still have some questions on a couple .21 motors I am looking at for a hyper 9. Just looking for everyones thoughts on these motors to help me decide. Please keep it clean and nothing personal! Thanks!

OS V Spec - I have read/heard they are fast but dont live long

GO Tech 7 Port - Heard they have carb issues/reliability issues

Werks B7 - heard its a good motor but has some carb issues as well

Thanks again!

I have had the b7. It is fast, but the carb has sticking issues. I now run v specs. The V specs are great so far.

I would go with the V-Spec of those 3. They last longer than most people say.

How long exactly are people talking about when they say the v specs have a short life span? Have they gotten better in the last year?

I would go with the go tech 7 port. I personally run that engine, i have had no problems at all with it. Great run times + all the power you would ever need!

I'd say your typical V-Spec gets about 6 gallons through it. Ive seen them last longer and Ive seen them not last that long. It all depends on your conditions and tuning abilities.

Pretty sure GO has updated their carbs, get it and then send it out to PTM (Pro Twister Mods) and have it modded, it'll scream!

I would go with the GO 7Port, with the newest Gen 5 generation, it fixes the carb issues.

I personally have only tried the Go .21 7 port which Is what I currently have. I have had no Issues with the engine at all. The only pain, like with most is running it in. As alot of people, say its a seriously tight engine. But yea, I would say the Go is a good choice, havent tried the other's. So cant compare.. but have had no issues with mine. And I get great runtimes.. 8 mins on average.. at im not exactly the most picky on my tune.. I run it slightly on the richer side.. for better lifespan. As Im only just getting into racing, but to me.. its a good solid choice.. for the price!

I am for the GO's but you have more choices than that. The 7 port is awsome on mid to high end and sufficient bottum. The 3 port is a beast too and is the newest designed mill from GO. The 5 port is a monster on bottum and with the right pipe screams all the way up. An if you want even better the EBM5 Fully race prepped by EB MODS there is 2 versions of that to choose from also. The Carb "issues" are like years ago. These motors will hang on the track with any other motor out there no problem, seen it did it and still doing it.

V-spec will probably last decent if you do not get it hot and run a little more oil content. Miss the tune and get it hot and your looking at getting it pinched sooner. Will not last as long as the other 2 due to softer crank and piston.

Werks, I have not ran one they have good materials. Not as popular around here as they used to be.

The Go would be my pick but not just because I sell them. Last spring we started running them and they have really been good. We have not had a flameout, get good mileage and awesome power. They really never had any carb issues, they tried running a long needle and it just made it tune different than what people were used to.

It also helps to buy an engine from your local hobby shop that has knowledge of the motor and can help.

Of the three you listed; I'd use the Werks, but spring for the Pro; they've revised the carb on it, should have no issues.

Otherwise you can find the Picco Evo3's for fairly cheap (200 down) and they outperform the Jammin'/Picco all around. Runs like a bear using a JP3 pipe as well and gets excellent runtime.

From what I've observed, GoTech seems to let their quality control wander a bit...so some are ok, some are great and some are duds...
