GRP... Engine... Thread...
 

So, I was curious how good these motors were compared to the Ninja line, But after watching qualifying for the silver state race, I'm impressed.

Drake, and Truhe were going the full 10 minutes + without pit stops. Pretty much every one who was running this motor didn't have to pit and it prooved to be the deciding factor in where the qualified. Drake TQ'd

What do you guys think. I plan on buying one for my next motor.

I also want to try one, but currently I am in love with my RB C6BB. The going rate with pipe is not too shabby either: $420.

It's hard to say, as I don't even know if the engine is available at retail yet, or what the asking price range is. If their tyres are any indication, it'll likely be a pricy mill.

go to horizonhobby.com

I REALLY like RPM, and would for sure sacrifice some bottom end to get it. They make a "rally-cross" motor, but I DOUBT I'll be able to find one in the U.S. when they release them......Sucks.:(

The carb looks identical to the GRP made Ninja carbs. I wouldn't doubt that these engines are almost identical internally to the previous Ninja models. If Ninja owned the rights and/or tooling to the design, wouldn't the OS made ones look the same as the previous Ninjas?

the new GRP engines are identical tot he GRP Ninja......... the new Ninja mills are completely new and off in a different direction......... I do beleive the engine designs were owned by GRP not Ninja....... the new GRP mills have the same case, port count, bore,stroke,carb,rod length,crank bore, crank coating etc....they may have tuned the port timings slightly but for intents and purposes the new GRP engines are just GRP Ninja's with a different cooling head.........they may not have been the best ontroad engines but they are fantastic offroad engines..

Does anyone know if the Losi guys are running GRP .28 or .21's in the truggy class at Silver State?

Lets see, this motor, holds a good tune,will idle all day,
has a screaming top end, never flames out, great run
times and a glow plug will last a season. Sounds like
my .21 Ninja to me. I've been running this motor three
seasons now and never had any problems.
Now just because Drake wins a race with it everyone
wants one? Thats friggin funny. I herd that he was wearing
a pink G-String when he won that race, you guys got to
have one of those too? Ha!Ha!Ha!Ha!.......

I have one ordered at the shop. Release date is scheduled for 3/20. It was 3/10 but you know how losi/horizon is with pushing back dates.

I already know this is the same engine as the ninja, almost. I owned the 21 B01 not the B01 A and was quite pleased with it. So it's not new to me. I never got the fuel mileage that this GRP motor has been getting. Myabe it's a motor/pipe combo that helps? It's also the same as the GRP Falcon motor

And I already had the pink thong, so I think Drake needs to thank me for the sucess!

kinda funny how much run time you can squeeze out of an engine when you lean it out to 300 degrees and use a 6.5 mm carb restrictor :nod: major runtime !!! and screamin , oh buddy !!

I would sure hope these things scream! They cost a freakin fortune!
Its cool that "The Drake" won one with it but I am sure "The Drake" surely didnt have pay for it...
Its still a little rich for my blood.....
I work for a living! I will stick with whatever I can get cheap locally...
No thanks!

I just noticed a week or so ago in an old mag with a test on a 367, and that is the head has vertical holes drilled in from the bottom. This would allow for more surface area to cool the engine, meaning you'll have to run a tad bit leaner than with the typical head to run at proper temperatures, yielding more run time.



Nice, but yeah, more than I'm willing to spend on an engine too.

All the pros lean their motors down to the maximum, please dont be an ass and try to discredit one engines accomplishments over the others.... a person would have to be pretty naive to assume only the guys running GRP engines were willing to lean down enough to get 10 minutes run time.. All pro drivers will be putting the same type of tune on all the other engine brands..if the GRP's had run time advantages they were due to engine design and not some tuning trick........ lean down a motor too far and lose power, the more fuel you burn the more power you make..leaning down past the sweet spot only hurts power and doesn't make them " Scream "

i have had one bo1 and i'm on my third bo1a. very pleased with grp engines so far! holds a tune very well, easy to tune. i can get 10:50 on a tank running under 260*f with a nice stream of smoke! i run on a small track, but thats the best mileage i have had out of a .21, by far. i consistantly break 10:30 with a "safe" tune. these times are also from a bone stock engine!

I don't think the Team GRP drivers were running
stock,out of the box motors. So, lets have a modders
contest. What modder can get the most out of the
.21 and .28 GRP motors? Grindfest '08,be there!

With one weekend of testing I increased runtime on a 7 port by 1:30 minutes in vegas over stock.... just takes some knowledgable tuning, nothing special.... I doubt an out of the box 'any' motor would make the 11+ minutes you have to run in vegas to go without a pit.

There's dozens of variables that play into the runtime external of the engine...driver has a ton to do with it

I've got well over 10 mins on a 50+sec/lap open tracks all over the country with my Vspec...and thats at a good tune, not leaning it to meltdown. There's no 'miracle' engine, never has been, never will be. Practice tuning with a bit leaner bottom than most, a low idle and you'll find your not at WOT nearly as much as running a rich bottom / lean top like most everyone runs.

did i say one word about grp engines being the only engines that this was done to maximo ? holy smokes man , why so defensive ? more of a statement about how they tune their engines in the super fast guy level .

thanks tony!!! but there are magic pipes !!!

Haha Monty I bet

Hoping to get up there for the Hank this year, man that race is a blast

So far, I have tuned an O.S. Speed .21 AL to 12 minutes of run time. I was surprised to get that time. When the car came in, I flipped the car upside down and no fuel in the tank. It shut off a few seconds afterwards. Temps was about 223F. This was at the Hurricane Raceway track. The same one used for the J Concepts RC Clash race.

Matt, I was under the impression that the new GRP line was going to be similar internally to the MR Ninja line but have a few extras that the mario rossi tuned versions had. Otherwise it's a pretty good price increase going from the Ninja for $280 to $420 for the GRP mill just because there name is on it. I'll most likely be picking one of these up this race season at some point.

Thats $420 with pipe and manifold mind you.

well its loud and clear your a die hard Nova fan.... so I figured you were taking shots at the GRP motors...i guess I was wrong my bad !!!

All this buzz about GRP motors. No dough they can build a quality motor! (And apparel) But there (GRP) strategie in signing up (paying) many top drivers to use there motor, is there biggest aset....:sneaky:


What wins on Sunday, sells on monday.........:nod:

Smart on GRP...

got that right :nod: advertisement paying off at its finest :D

Nope, $400 for the motor and $500 for the motor/pipe combo...

I'm sure he was thinking of something else when he said $420.:smile:

Driver finesse... drivetrain efficiency, tuning ability, weight, tyre footprint, weight transfer under acceleration, aerodynamics, enginge age, fuel type and of course type of engine and colour of G string.

Every little factor adds up in fuel effeciency. Same as the set up doesn't make the driver and a good set up with a bad driver isn't going to go places either i guess.


If i was in the market and had the cash to flash i would be curious to run a GRP next to the new RB which looks pretty sweet.

$420 for the motor,pipe,shirt and hat. This pre-pay
deal was offered on another site by an online store
that advertises on the site. The short time offer
was for members of the site only. I already have
.21 and .28 Ninja motors so I let the deal slide.

Interesting all the above point of views, but ...

We all know about advertising, about great drivers and what they are able to do, the real question is how is the product going to perform in our hands?

Only time will tell.

Cota, I think you speak some truth man.
Most of them are flavor of the day people.
Pros in a box, in a month most will be bad
mouthing GRP motors to cover there lack
of driving. Blame it on the car,motor, tires,
fuel,clutch set-up...............
Cry me a river!!!

Ouch! And that's just for an off-the-shelf mill that's likely 98% identical to a Ninja that's easily $100 less. For what you can spend on the GRP unit, you can get your Ninja custom race-tuned.

engine prices are getting way to expensive. Im runnning a collari 3 port engine in my 8b , thing screams faster than my vspec. I dont think I will ever spend over 300.00 on a engine again

I sure hope these engines aren't $400.00..... I own the GRP Ninja 28 and FLS pipe already...but I would not pay any more then I paid for my Ninja...... the MR tuned versions would be very mildly touched and not worth the $100.00 premium.....

I agree with the expensive part. It's hard for me to buy an engine that almost costs as much as my buggy. I'd just kick myself even harder in the A$$ if I blew it up.

I just ordered me the .21 tuned promo kit, i reakon its very well priced, set me back $550AUD landed, which would be the same price as if i bought another boss engine (what ive been running) and a new fls pipe, so im getting the goodies it comes with free. Ive run the grp boss for the past yr and they are better than anything else ive tried lately, especially when it comes to QC, no doubt these new grp's will be the same.

Actually no... screen name does not match the person behind it:batman:

its $420 if you know how to shop, and $420 is great for a top of the line motor with the proper pipe and manifold included. The 367 set me back $450 when i got it and thats without the manifold. A OS Speed motor is $430 without a pipe, add the 2060 pipe and its $560. Also i hear theyre releasing a sport version of the motor for those that dont want to pay the extra bucks for the race version.
