remember though just because you have the fastest engine doesnt mean your going to win its all setup and driving skills

Amen! On another note these reports of v-specs not lasting long and bearing failures, all it boils down to is people are not learning the v-spec. It's not just a nother .21 You can't just go by what you've done with all your engines to break the v-spec in and tune it for optimal performance. When tuned properly, yes it is a beast and yes you should tune the mid-range as well. If you think it's something else, contact o.s. engines and ask them why they haven't revised the engine and released a second version. Ask them why they haven't improved the bearings. Don't get me wrong, all these other engines are strong. I'm not knocking them at all. I've seen them all at big races and every one of them win some and lose some, including the v-spec. It all boils down to the driver. I'm sure Jared Tebo could spank a hefty percentage of people in this forum with their latest and greatest engines and buggies while he uses a pull start gs racing 21b01 powered duratrax axis. I believe he'd still beat alot of pro's with that set up too. Bottom line, up your skills. That's going to win you more races than any buggy or engine.

Personally, if your going for "THE MOST POWERFUL ENGINE" then you'll need a chassis that can take the power. The stock MP7.5 WILL shear the drive shafts, strip the diff internal gears, suffer from lack of braking, snap shocks, lose arms and generally just fall to pieces. Better to get a top end chassis to match your intended engine. If you can find a Black Magic, that's what I'd go for. But the V-Specs are reliable and powerful, I've seen 2.94 Bhp and a top end of 44,100 rpm quoted on dyno tests. Certainly not to be sniffed at.

Adam, just because I like something does not mean you have to be unimpressed by it.

its just calling it as i found it, no hidden agenda
if you recall you were spanking your monkey over your Picco P7-R for ages & at first i was unimpressed with mine but as time went by i grew to love that engine & it was a sad day when it got toasted & had to be replaced[&o]
i've bought 3 V-specs now & have yet to actually run one in my own car as the WS7II i fitted at Holbeach 2 day National back in May has been absolutely flawless & just keeps getting faster & faster!
i've sold 2 Vspecs NIB & have kept one for next year or to use maybe during winter for a no stop fuel strategy in 10 minute finals (dependant on daylight left in the day of course)
the engine i tried did seem to be a very smooth drivable engine & would probably improve my laptimes no end BUT i prefer something that gets the buggy up on the pipe & screaming as soon as you pin the throttle & for me at the moment its the WS7II (just bought another one yesterday) and the long time favourite the 421B
i did use my K2 the other week with the C4 & that is a seriously fast engine too although a little too thirsty by todays standards[>:]

for my money you can't beat the reliability & quality of an RB or a Novarossi
the OS is good but pretty much everyone i know who's been racing them this year have all gone back to an Orange or Purple head for next year

in case you were interested Russ @ Top Options is doing P7-Rs for £150 atm!

OK, I still love my P7-R but am just waitng for winter to run it again (it's suffered from losing 2 fins as they all seem to have done), Accell wise it leaves the V spec behind, but the way in which the power is laid down so smoothly from the V is just perfect for my style, I just dont have to brake, I can run right up to a bend, lift off a bit, cruise round and punch the exit, so smooth, so reliable and so easy to start.

I would take up Russ' deal but I bet they're series 2 models with the dodgy cranks.

the head off a Vspec should fit your Picco!
i say should as i've not actually tried it but i have seen a Picco sponsored driver using a Vspec underneath his Picco head (can't upset the sponsors) BUT i've checked his car last 5 meetings & its been a Picco in there again! i suppose he was just testing it & prefers the punch of the Picco!

Might try that when the OS starts slacking. As long as the bols line up then all should be well. Thanx for the idea.

Id say the Rossi LSK would be the one to get..you might wana take others advice and upgrade other stuff before dumping a sick engine into your car..i think i seen that LSK on ebay for about 290 buy it now..best price you will see

S421BNXmod....Hands down is the MEANEST MILL I've ever seen......It sounds like it's eating the clay off the track and spitting fire from it's ass in pain......but if you are running a Inferno sport now instead of getting a mean mill that will kill your car, you should look at getting a race proven rig and get an RG or similar engine till you're ready for the big dogs......the P5 is what I run and it stomps on Vspecs all day......more reliable and much easier to tune IMO.......take the advice people here are giving abou tuping your skills first though......I put an RG in my buggy and go play at the track and still run people down.......it's amazing what those little engines can do when tuned properly....and yes I said RG....that crappy $100 OS engine......out of all th eengiens that's the one I'd recommend th emost....cheap and durable, great powerband and super easy to tune...I keep 2 in my box ready to swap out any time.....

No way, the greateat mill without any shadow of a doubt and I have this on the highest authority is.......


































































The Team infinity Samurai 521. If you can handle the power of this beast then your ready for a Hyper 21 4 port.

couldn't see the pic for some reason. Do you really rate the 4 port or is that a sarcastic remark?

it's a sarcastic remark, the space between the 2 phrases was to build up the tension lol

I payed about $400 for the V-Spec when I bought my 777, got a bit of a deal, I got a sweet deal on the C5BB though, payed just under $600 Canadian for it and I've seen it for over $600 US. If you want to spend the money, IMO this engine is great, easy to tune, holds it well and rips the track apart.

Cheers
