I love(d) my Piccos, but I still want to try a C6 clone. I've seen them at races over the years, and have always found them impressive(sidenote: I do like what I see from the BX-R too, but I don't do that price-class for engines..) The video of the Blast V8 I've posted before* is also impressive - very, IMO...

I'm currently breaking in a modded P5XLT, and on the 8th tank I started getting on it just a tad, and so far I have doubts that it will amount to much. Could very well be wrong on that - may well need a different pipe and more fuel through it.. But I have a clip too of my Fire 11 in the same car with same pipe, gearing, etc.., and the Fire IMO is noticeably more impressive. So far I really REALLY like the Fire(probably tied with my Picco-Jammin/Nosrams for fave engines I've had..), and would maybe get another one instead of a Blast if I could find one.. But I dunno', I'm just really keen to try one of these C6 Blasts... Everybody raves about them, I like what I've seen personally, and the price is right..

A Fire 11 is a very aggressive engine.....pretty much as nasty as they get

the s7 based line of engines like Fire 11, have been great for over 15 years. lol

How are you basing that the S7 is similar to F11 ?

Look at the part numbers of the PSR. 01143. Been that way for over ten years (maybe 15). Now there are some extensions like s7, ws7, ws9 etc. Probably different piston materials/design over time. Like I mentioned before, I really don't think RB has had a new sleeve design since Rody left in the mid 2000s. Now they have changed names, packaging, coatings, anodizing, heads, etc. But from what I see the same base PSR has been used for years in the S7, WS7, WS9, F11 line and C5/C6, B10, B11, BX/R etc.

Lots of different revisions in the crank and bearing sizes also.

You see many many more engines than I do, I am just going off of part numbers.

Any input on the C5? Milder than a C6 I assume..

Never had one, it was similar to the C6 though. I don't know what a mild engine is and would never buy a mild engine anyway. lol

Between the adjustability of the RB carburetors and all the standard and oval carb inserts any of the RB engines can be tuned from extremely smooth to very punchy. I run the BXR with the 6.0 oval carb restrictor. It has plenty of bottom end and still has a smooth and linear power delivery through the rpm range.

The RB engines also last a very, very long time. I don't race as much as I used to but I am still on my first engine that I broke in for the DNC in February. I would guess it has around 5 gallons on it. Still has a lot of compression but I will change the bearings before the next big race. I imagine it has another 2 gallons of life left in it. I'm very pleased with this engine.

the only diffrence between the c5 and c6 is the c5 has higher exhaust timing
making it very picky on the clutch as the power comes in higher up in the revs
and comes in hard. were as the c6 will pull from very low revs is better on
fuel and feels nicer to drive the c5 proberly has a little more over all power
but getting it to the ground is harder.

New? Another engine made of old parts I guess...

Not necessarily, RB was never big in the 3 ports. They had a sport s3 engine, but their offroad race engines were the S7 based engines and the C6. So I doubt they have a bunch of 3 port spare parts laying around. This could be an S3, with some high end parts though. Maybe newer designed case... All speculation though. Should be a good engine. But for the money it is hard to beat the blast at just over half the cost...

pretty sure its new. couldnt imagine RB making a Kanai motor with spare parts. Im sure he had a hand in the design.

never seen a RB Products 3 port With MES 3port exhaust before, if thats old parts, it has never been sold before :-)

Intrigued :-)

No more Blasts at Amain.. :(

A few years ago they did the X10 which was a 3 port: http://www.rbproducts.com/explose/RB.../01010-X10.pdf
Probably based around this but with a 14.5m crank?

That's right.. The X10 was pretty popular over here I think..

the Shark was also a 3 port with MES exhaust !

I thought so too! however when i checked the spec sheet its not?
http://www.rbproducts.com/explose/RB...10-SHARK10.pdf

the Shark was most definitely a 3 port......at least the original versions of it were.....

The shark 10 which was made for Reno was a 5 port engine... I think rb had another engine called shark... Not sure

Shark 9 was a 3 port

it was a 3 port for sure , I worked on a couple

http://www.rbproducts.com/mainEn.php...esentation_int

Shark 9 was a 3 port...

I had a shark 10 that was a 5 port...

Ah i see they are different between the 9 and 10 models.
The Shark 10 has the same part number for the liner as the X10: 1146-33

Correct

So was the Shark 9 a good 3 port? Thoughts on how the Kanai engine will perform?

The Shark9 was my favorite RB in buggy. The Shark9 also had a balanced crank in it, not sure if this Kanai engine does. My only complaint on the 9 was the L2G cooling head, and that Kanai has the newer taller heads so thats awesome. With a 2058 pipe that engine was an easy 10 minute pit stop engine on any track I raced on.

So the 3 port Shark9 motor was a crazy bottom end motor?

No, not a crazy bottom end motor, it was a great usable powerband in a buggy. I never tried one in a truggy because thats where the C6USA did it's work, because I knew that was more than I liked in a buggy. IMO the Shark would not have been a great choice in truck, I am sure it would have worked but I can see myself wanting more bottom end in truck than the Shark provided.

Is the V13 identical to the V12 and V14?

Ok you scared me enough into buying a V11 Blast from absolutehobbyz.com they had one for 179.99 still. Looks like I got their last one.

BUT they still have V12 for $199.99 if you want those. Nice place to buy from. AUG25AHZ is 25 off 250 for AUG12AHZ is 12.50 off 150.

I see folks on here really liked the V11. After I reviewed the parts PDF more I see its actually a crank from a B9 and piston/sleeve from a B11. I've had both these engines and always paid $300+ for them so for 179.99 that's a great deal.

Ya, AH is good. Store isn't quite as polished as Amain, but hard to compete since Kendall is a programmer and customizes everything as needed. Sucks there are no more V12s but I bet the V13 or 14s will be in stock soon. I know there is a V13, not sure what the differences is between them though.

Looking to switch engines for NeXT year, but the RB univers is very difficult to get a grip on...

Here is the datasheet for the blast V13. anyone can figue out what engine it is based on?

Thanks!

glad i got my V12!!

When I asked my guy about getting another V11, he just laughed at me... :(

The modded V11 in my truck is ridiculous. The thing runs harder than my Boost .28 when leaned out a tick. Added a bunch of fuel back in just to make it an easier drive. I was pitting at the 8 minute mark, just to be safe, but after a 7 min qualifier I had about a 1/3 of tank left. I haven't temped this thing since the 2nd tank on the box. Well, I have temped it once getting it back inside, after being off for about 3 minutes, its at 180 or so.

Why did he laugh?

Got some info on the Blasts from Pete at Answer-RC (this dude has always been really cool and helpful in my experience..). I think though he mixed up the versions in the first sentence here, since in data sheets it clearly states the V9 is based off the C5...

"Both the V9 and V13 are long stroke so more linear than the C5 as they are long stroke (the C5 was short stroke)

I’ll be the first to admit that it gets rather confusing with the blast series.

One of our guys at the UK nationals this weekend gone was running the Blast V13 having previously been using a BXr. Though not quite as aggressive, it certainly didn’t seem short on performance by any means with a 2045 pipe on there and we had him on a 10minute run in the 20mi final on Sunday (he came in at 10:13) though in fairness it seemed a run time friendly track as I know one guy whom had calculated 12:40 run time who can’t always do 10.

Regarding the Blasts, we have had the V13 but looking at the data sheets for the V12 they seem to be identical in all aspects other than the crank (01167-14B on the V12 as opposed to 01167-14B1 and on the V13) certainly they use the same P/L/R set (01167-504) which is a 5+2 with MES though with a relatively small exhaust port which would suggest why they are smooth in power delivery.

01167-14B1 as per the V13 uses 1 tungsten balance weight in the crank.

I can’t comment on the V14 as I don’t have a data sheet nor can find one on the net, as we have never had the 14 I’ve not looked strongly into it.

On a side note there is also a V15 which we have a small amount of but have not publicised which uses two tungsten balance weights on the crank (crank part no 01167-14B2) but retains what is now seemingly the common to later blasts 01167-504 Piston and Liner set.

The V15 also uses a black crank case as opposed to the silver on the V13.

Hope that sheds some light on it for you."



Re the V9 vs. the others:

"To describe it as a on off switch is harsh, they are reasonable progressive and can be made more so with correct clutch tuning.

The V9 is certainly more aggressive than any of the later ones though I don’t think there would be much in between 11-15 though we haven’t had them all, less so run them all so I can’t give any concrete info.

I think you will struggle to get a definitive answer comparing all Blast variants as no country has had all variations."

A C5 is a long stroke, not a short stroke.....

Was just coming on her to say that
