Turbo or SC?? - Pros/Cons

[kinger]

Oh if you get ARP head studs follow the directions on how to install them from the shop that you buy them from, I had a bad luck with them because I tq'ed to factory spec and they like much higher. Stock studs are just fine for 10lbs. You make the call. IIRC they like 45 ft-lbs and people have stripped out the block at 44-45ft-lbs before so be VERY careful and like I said follow who ever sells them to you exactly how they say.

i was also thinking about fabbing up a fuel tank for under the seat.....

has anyone done this?....i think making a low long tank and removing some foam from bottom of seat,something like that...just a theory at this point.

it sure would be nice to have an extra 3-5 gallons for trail riding....

You would probably be better off making a custom seat that is lighter anyway. Another guy on here made a custom tank that fits on the extension of a 136 and it was connected to the front tank plumbed so that it would drain the back tank first and the guage would read full for ever till it started using the main tank. I'm no entirely sure I need more fuel yet but have some ideas in case I do.

Jamie,
You had that pice of junk kit from the mountain kit builder like I had that one year and ran extremely hot! And it didn't go in the field, just like mine and Need For Speed 2's. They ran pretty poorly, showing good power on the dyno but going nowhere in the field with lots of issues to boot. Never had any issues with my Simons CPR kits on any of my sled like that, just dead reliable with none of that heat issues like the other "altitude kit".

I'll agree with you that that brand of turbo kit was an overheating awful mess. None of the Simons kits acted that way for me.

It sounds as Dan has his mind made up on a supercharger anyway, so it's a moot point. Just wanted him to know it's not going to be the most powerful machine and warn him of such, I know he likes speed.

Mike I totally understand what you are saying,and I really do appreciate the input,its good to hear all sides and i know many turbo guys love their kits!

I think im more worried about trail-ability then the almighty HP numbers in this case...i have been warned by several MPI trail guys to stick to low boost(5psi) and call it a day,since it will be plenty on trail and economy is much better.

I know for sure if I was NOT needing the headwork,i would be running stock head and studs for first season on 5lbs,then move up next season .....but since i need the headwork now,i figure i may as well go for 10lbs right off bat.

in general,boost is boost......which i think is the main thing im excited for....and if its tinkerproof and reliable like many have said,ill be very happy.

thanks again for all info!

I have to agree with Ernie and Jamie here....

from all my research about trail riding/flatland all seem to say SC is the way to go....corner to corner response and NO HEAT is the big thing....

and ernie is right for sure about the MCx...i have seen that mcx run on flatland and plain work!....no heat being a rear mount and lots of power.

however with the MCx or any turbo,the SOUND of the modified exhaust WONT FLY in muskoka....

Muskoka where I ride is a huge tourist area,and the cops come down harder there then anywhere in ontario IMO....even if your sled is quieter then stock,they will ticket ANY MODIFIED exhaust now....and we all know these turbos arent quiet.

I have pretty much come to a decision on going with 10 lbs setup with stage 1 blower and a cometic headshim with RB3.

love to hear all the pros and cons,and that is what makes these forums so fantastic....

looking so forward to radaring with all you ontario BOOSTED boys this winter....north bay or on my lake,when the ice is good ill have the gun!

Dan

Hey Dan are you still running that RTX what happened to the spray I thought you had that thing running pretty good? If you really wanna play you could run a stage 2 and pulley it to 10lbs for the trail and 16 on the lake and look out. The GEM box is fine you just need to get use to it. Gotta say I love the bike! Ive got your old screen name and I also have a 03 V-Rod gotta love.

I heard Simons was not doing Turbo's for the general public anymore? Not sure if this is true?

 

[TurboJamie]

thanks ,great info Jamie....

are you running a turbo now?....maybe we can hookup this winter for some riding since you arent far from me....my cottage where i ride is on Mary Lake and I love liskeard area ,especially when our snow melts its nice to head north in march.

When i blew my motor 2 season ago with NOS i did some major damage,got a new block,one piston,one rod and all bearings and rings ect....

the block was blown out or round on cyl 3 bad,and my head was out abit too,but not bad enough to not run stock motor.

So ive been running the stock motor for 2 seasons since fine,but i know with BOOST that slightly warped head will come back to haunt me.

So since i need head planed, I plan to go with ARP 10mm studs,and figured it just makes sense to do the headshim now while im there. i guess thats why i feel i might as well just go to 10lb boost setup right off the bat.

Hoping with the new MPI BOV and a good RB3 tune my economy will be decent.

really cant wait to get this project going!

Dan

Dan I sold my turbo apex. Do not buy I head shim I have one from a Powderlites kit you can HAVE. Then you can run 10 psi on pump gas no problem since you have the head off stuff the shim in forsure.

You can either come get the shim if you are in the area or? Just don't want it to get kinked or something shipping it any ideas?

thanks for the offer!..that is awesome,where abouts are you exactly?....im considering having Dave wrench my sled,since i need head trued anyway.....how far are you from prescott?....

if you arent too far...you could send it to him and Ill slip you some bucks for it all and make it worth your while....is the shim not metal?...i thought it was?

Dan

I'm IN stouffville just north of Toronto. I can send it maybe between a couple pieces of 1/4 plywood or something. It is metal.

 

[Skydog]

Yea i liked my MPI but need to do a few things to get it running to my likeing. Rb3, Bov,cold air kit, add nipple to cooler for the air by pass hose. This was on a Nytro so it is not the same.

yep still got my 06 RTX....blew my motor end of season in 08 with that damn NOS...i will stay away from that now!..lol

yeah im just thinking about that now....i thought stage 2 i could only run BIG boost numbers but if i can run 10lbs with stage 2 blower,then change out pulleys for radar days i might consider that too.

holy crap you got a Vrod too?....do you hangout on www.vrodforums.com (1130cc.com) My entire custom build I did last spring to my Vrod is posted over there,i hangout over there alot so check it out,look my name up there...rockerdan.

also,click my signature below to the PICS!....and if you like Vrods,check out my video here with my custom fender and 300 tire!

thanks for the offer!

Ill let you know when i find out exactly what im doing in the next few weeks....Still waiting to talk to Dave and figure out where i want to go with this project.

thanks alot Jamie!

[ROCKERDAN]

Ok another question.....

lets say i want to run 10lbs with my dailey driver,headshim and 91 octane....all should be fine.

now what if i really want to go nuts for radar day after awhile im sure ill want more and more!

I am pretty sure the stage 1 blower cannot go higher then 10lbs right?

if so....would i be smart to get a stage 2 blower right off the bat?.....can i run a stage 2 at 10 lbs same as stage 1??......if i change pulleys to run HIGHER boost then 10 for radar day,what would I need?....race fuel I assume?...would I need MORE fuel delivery then???

I guess i am looking more down the road now,and think if i MIGHT want more later,i should have this setup now so i can do it later....

I hate to go with stage 1 and 10lbs,then after a season want to go 14lbs or more and never be able to do that with the stage one ever.

thoughts??

thanks!
Dan

Rockerdan I love your bike, verynice, as for the s/c be prepared for terrible fuel mileage, I also think that the new turbo kits are miles better than the ones some of the guys are quoting experience on . I would myself would go with a front mount Powderlites, It has the RB3 way better double down exhaust system, larger injectors, 2860 turbo, heck you can even puit twin hindles out thev back looks and sounds stock. !0-14 lbs of boost for thousdands of miles./ Dave has the new 4 tube headers for the apexes they are very nice . Just my opinion, I did have a stage 2 mpi with a shim in it running from 12-18lbs, always got my azz handed to me by the turbos on quarter mile runs, trail riding in the group I would get 80-85 tops for mileage.

 

[kinger]

Yeah Dan in theory you could do what you say on the stage 2 SC but trust me when I say swapping pullies is a major PITA, you have to heat them up and use a puller to get them off who know how long the pullies and shafts would hold up. Just my opinion the SC is more of a set it and forget it type of boost and hence why I went that route.

If your wanting full adjustability you may be better off with a turbo. Just remember when adjusting boost EVERYTHING changes guys like to quote on here that you just turn the dial but its not like that, you need fuel, possibly timing, and clutching to match. Some guys under rev on the trail just so they can run high boost on the radar runs. I dont like that for my type of riding.

If your looking for max speed turbos are it; no one will over argue that just be ready your fuel tank gets smaller, exhaust is hard to keep stock, heat, headers, etc.

I'm sure they are better now after this many years of tweaking but I wouldn't say they are as tinker free as a SC.

BTW HOT HOT HOT bike, I'm not into bikes but that thing rules!

Problem where i ride will be cops with exhaust modified,they ticket even when its quiet unfortunately.

did you run the stage 2A or 2B kit?....i was checking MPIs site and i see the 2A kit is about $5495 while the 2B kit jumps to $6495 .....it looks like they add a upgrade to fuel system with a pump ect...

the 2a kit says it runs at 14+ boost...but can i run that stage 2 blower back at 10lbs if i want?

Id like to go with this 2A kit setup for 10lbs,headshim and 91 for trails....then also have pulley to swap up to 14+ boost and then i guess i would need to add some race gas for 14boost right?

thanks!
