blower better than turbo?

[superschlamper]

im in the ditch a lot
river as well
playin in the drifts
still want the speed at top as well
is a blower the better way to go?
put 4-5000 k's/year
want reliability too
need to be able 2 run 87 oct when theres no other choice

I don't think you can really run 87 in either, safely.

I run 91 in mine which is better than having to find race fuel.

I like my supercharger. instant response, great power. It has great top end as well.

Make a search. The debate has been going on for the last 3 years. I vote for a turbo but that is what I run. A SC works well and so does a Turbo! I would not recommend running it on 87 no matter what, but if you have to... stay out of boost, can be hard with a blower, easier with a turbo.

I think there is a place for each. to run pump gas which would be important to me you would have to run 7psi with the supercharger or head shim and 10 psi then you would be 200 220 Hp or run pump gas with mc xpess 290 hp both are great. I hear the supercharger is a little better response and about 2300.00 cheaper than the mcx kit . there are trade offs for each system. some better than others like the others said do a search and pick your path

Which MCX kit is 290Hp on pump gas?

Thanks.

Thanks.

The base kit went from 265 hp to 290 up dated mcx for 2008 The 16T is no more and standard now is the 19T

PFFFT You turbo guys NEVER get anything right. The debate has been going on for 4 years!!

 

[rxrider]

hahaha you got it....make it a lifetime, since both are old technology that has been around since the days of the WW2 fighterplanes and in the cars for ages as well, LOL no that's why we turbo guys stick with em turbos....to get them right, I'm in my 4th season trying to make it right hahaha

I have had both apex stage 2 blower and several turbo kits. My preference is the turbo, as for response the turbo knowledge out there is vast and the old response thing is mute issue in my opinion, out of the hole you only have so much traction avalable, head to head a good set-up turbo will move with the super not spinning the track as much and from there say good bye turbo is going very quick in the midrange due to one of the better things it has max boost in the middle where the charger is linear. Gas mileage is no contest turbo wins, Way it out for your type riding but for me my turbos will do everything and more than a super. Clarify this is my opinion based upon my knowledge of owning both.

ditto !!!!!!!

currently thinkin blower is 4 me
my understanding:
turbo lag in begining-blower instant power
turbo spools in mid to high-blower 4 lengths ahead (hole shot)
top end turbo has it(free power-exhaust gas)blower will hit top of power band
ditches....turbo has lag blower power on demand blower better 4 ditch
im guessing i wouldnt notice the diff. betwween them just like that

You haven't said what sled you're boostin'

Listen to what Need for Speed 2 says on the turbo lag issue.

On the RX-1 and Apex engines the best kits makes boost as low as 5000 rpms and hits max boost at 7000+ rpms. As you can see turbo lag will only come into play drag racing from a standstill. When riding slowly you are always very close to making boost and then there is no lag. If you're running at 6000-7000 rpms giving it WOT you have max boost instantly while on a blower you will have to get max rpms to get full boost and power.

I don't think a SC will jump a well tuned turbo much if any.

When up past 6000 rpms you have max boost on demand wacking it WOT.

Choose what you believe in, both systems work well. Continue reading the Turbo & SC forum, all your questions have been answered numerous times the past few years.

Happy boostin'

You are mostly correct. I owned a very good running turbo'ed RX-1 for 4 seasons and last year put a SC on my Nytro. I do not have the Nytro fully dialed in yet but here are my observations.

There is a definate diferrence in lag. I didn't think so until I owned a SC. You will notice it when accelerating at almost any speed although the higher the rpms the less obvious it is. When taking off from a dead stop you will certainly feel the diferrence but the instant power of the SC causes traction issues like rxrider says which may cause you problems. Anytime acceleration is involved the SC has the advantage for sure.

Top end power definately goes to the turbo. With everything else being equal the SC needs about 3 more pounds of boost than the turbo to compete on the top end.

Adjustability goes to the turbo. boost can be changed with the flip of a switch or the turn of a dial. SC requires pully changes which cannot be done in the field easily.

The turbo will maintain its boost at diferrent elevations and the SC won't. The SC is driven by a belt and it's max output is limited by that RPM as you go up in elevation and the air thins the amount of boost for a given RPM changes threfore the SC loses some boost as you go up. The turbo (assuming it is big enough) self adjusts through the waste gate to make sure you still have the boost you desire.

Fuel Milage goes to the turbo. I do NOT have a BOV on my SC. The average ride for me in the mountains shows about 7-8 mpg on my SC Nytro and on my turbo RX-1 I was usually pretty close to 10.

Under hood heat (if that is a concern) is a SC advantage. They definately run cooler.

In most cases low sound levels is a SC advantage. Since you are using the OEM exhaust it is amazingly quiet. Most turbos range from somewhat loud to obnoxious.

I'm sure I have forgotten other diferrences, but there is a good start for you. It may sound like I am down on SC's since more of the items above put the turbo in the advantage, but I am not saying that either is better than the other. IMO if you want throttle response for ditches, boondocking, or anywhere that acceleration is key then you should look at the SC. If Top-end and the most power per pound of boost is what you are after then definately go turbo.

turbo spools in mid to high-blower 4 lengths ahead (hole shot)

Huh? Where did you get that??? If 4 lengths was the case, NO ONE would use turbos except for speed runs... Heck, a stocker would pull a turbo sled then, too.
