What's the stock horsepower in a 2000 D2? What are some relatively easy things to do to increase it?

Thanks

chip it or regear the R&P when you put in lockers, or both.

you can always port the heads, add a supercharger, etc.

I think is 134.0 Kw / 182 HP @ 4750 RPM for a 2000 D2 I could be wrong though!

I hope you are not right Gus, I think that's the kind of HP my 96' has - if I'm wrong then it explains everything� last Sunday on the way to the trail head I had a 450 pound lady sucking on an O2 cylinder riding a 'rascal' pass me, but then again I think she had one of those AOL optimizer things attached�

Gary � the answer is stickers, it's generally accepted you will gain 5-30 HP per sticker. The 30 HP stickers are hard to come by, good luck.

Stickers only increase HP on Honda's and Neon's.
Stickers on a Disco increase trail ability.
My "Got Rovertym?" sticker has gotten me out of many a jam!

Cary - the stock 2000 D2 has 188 HP. There's not a lot you can do "easily" for significant HP increases. Like the guy said, you can chip it for around $400 (for the chips I've priced). The biggest bolt on boost can be had with a supercharger, where you can get up to maybe 50-60 extra ponies - depending on a lot of variables and which supercharger you go with. But, we're talking $4K, or so.

I'm a firm believer that the biggest power robber of the Disco is the gearing. A 5,000 lb. vehicle with a 3.54 final drive is not going to have much get up and go. So, I'm with Pugsly -regear the ring and pinion - 4.10 and 4.70 are available. It won't make your Disco top speed any faster, but it will make it peppier -especially when loaded down or passing.

If cash is a problem go with the stickers. they at least make you feel like you've got more power. :-)

Help the engine breathe, simple bolt-ons such as CAI & a good flowing exhaust will help. I think a chip is a waste of money, and if you leap into strapping a blower on it, be prepared to prep your fuel system, and later down the road maybe find your self yanking the motor to replace fried rings. Funny how I asked this same question in another thread, and no one gave me any feedback.

I put my disco on a dyno and got these results: replaced the stock air filter with a K&N and got an additional 2HP (that's a measley 1% gain). Tried adding a cold air intake with the K&N filter and gained 4HP over the stock setup - a measley 2% gain. The performance chip boosted the HP by 28 extra ponies, but I decided to spend the $400 toward the 4.10 gears instead. I went with the K&N in the stock air box because it's better protection in off-road conditions. I ditched the cold air intake because it's so vulnerable to dust and water off the pavement. I would recommend to anyone thinking about cold air intakes to take the $300 and spend it on a snorkel with a K&N filter - if your going to spend the money anyway. The snorkel has the same benefits as the cold air intake but draws air from above the dust and water elements.

High flow exhausts are not a bad idea but you get very minimal gain for the dollar spent. There should be no problem with overheating using a supercharger if you use your head and don't over do it. The Eaton models 62 and 90 don't even require an intercooler with the 4.0 engine. The models will boost in the 4-7 psi range. NEVER go with a Turbocharger since there's always an operating temp increase. Besides, the disco has enough lag time during acceleration as it is.

HP figures can be misleading. Remember to keep in mind your truck only produces max horsepower at 4500 RPM or something, and this doesn't necessarily represent HP at the wheels. I can't think of too many times when I've been wheeling with my truck pumping out max HP.

Chipping and mods like that are for ricers who want to shave a half-second off their quarter mile. Spend your money on things that will help actual off-road performance, not superficial graph results.

If you want a lot of HP, you bought the wrong vehicle :-)

David brings up a good point; forced induction devices are notorious for lag... it will be even more pronouned on larger displacement engines as the devices take time to compress enough air to fill the cylinders. Save the supercharger for your Civic and get yourself some nice tires for that Landie!

torque is what moves a heavy vehicle not horsepower.

by changing the final drive gears you can increase the torque at the ground where it counts.

with the 94-95 trucks you can also retard the spark to add low end torque and allow the use of lower octane fuel . this will also make the truck drive nicer at the low speeds that you most often see off-road.

anyone installing a snorkel ever get concerned with the fact that even though you now have the intake up around your eyelids, the truck still has fuses and relays (and CD changers) under your butt?

hey guys im new here, but i just took the 2 stock mufflers off and replaced it with 1 magnaflow, made my own cold air intake, and deleted the stock fan and put an electric one in...noticed a difference. but where can you get superchargers?

I know Eaton makes a blower for a Disco, also there are a couple others out there.

i saw a powerdyne kit for $7,000...what a joke, and i went to eatons site, didnt say anything about rovers...a home made turbo kit might be a good route to go

Powerdyne superchargers are crap. I've got the info. at home on all the blowers for the Disco. I'll post it up later. I don't think Vortech makes a centrifugal for a Rover? Their great blowers, I've got one on my Mustang Cobra and it's lasted a long time without any problems. You might check Kenne Bell, they make a nice twin screw roots blower for most applications.

I guess I don't really need more HP after reading some of these posts. The problem I see when wheeling is on easy trails sometimes I have it in Hi-1 and almost get stuck or run out of power it seems. I've never been stuck in Lo-1 ever. My brother in his stock 89 Cherokee never has to switch to low to get through some of the same stuff, or so he says.

My Disco is completely stock except for the OME suspension and tires. So far it seems to do everything I need it to. I guess lockers and re-gearing would be the next step.
I guess my next question is what are the differences between the different kinds of lockers? They seem to vary widely in price.

Thanks again

i looked at kenne bell, they dont make one. it would be nice if vortech did, my rover with 33 inch tires can barely pull it self up a hill...its real sad. gabe i also have a vortech on my 96 cobra!

Cary - there are good articles at greatbasinrovers.com (in parts/differentials) and at expeditionexchange.com (look there for tracktech products) on what different type of differentials will do for you. And no - there isnt much choice - TrueTrac, Detroit, ARB are about only kinds around for your Disco.

Also - thats why its 4H - its high range. If you going onto steep climbs you most likely will have to go for 4L, that is what its for. 4H is mostly for flat surface offroading(dirt roads and alikes) and mudding. Your truck is heavy enough to need low range to get onto certain stuff.

No kiddin! I've got a 96 Laser Red Cobra, I just got through rebuilding my block with a forged bottom end and a just had a fresh dyno tune. It through down 452rwhp & 402rwtq., I figured I couldn't keep driving it daily, so I bought an 03 Disco for a daily driver. What mods do have on your snake?

you can see everything at www.cardomain.com/id/callmecobra96
i bought the rover to have a little fun off road and drive daily, to keep miles off the cobra, but with the gas mileage ive been getting, i might use the cobra as the dd!

Very nice & clean. We pretty much have a similar setup and same Cobra, except for the aftercooler. Couple of months I'm heading towards blower cams and port & polish my heads, and strapping on a 3.12 pulley. After a dyno tune, I hoping to hit 580-600rwhp. BTW, what kind of seats do you have, looks good.

The recommendation to buy a snorkel instead of a cold air intake (if your going to spend $300 anyway) was in reference to CLEAN AIR, not water crossings. The snorkel accomplishes the same thing as the CAI systems, yet gets you above the dusty elements. I've yet to have any electronics around my butt go out due to dust.

Thom Mathie - Amen on torque. And the most cost effective way to achieve it is by changing the R&P gears. The rover 4.0 has a little more in reserve than the stock gears can tap into. I just used the HP numbers from my dyno testing to give everyone a chance to see some REAL numbers, not a guess, and not what a CAI manufacturer says. Some vehicles will get better results with a CAI than mine did - there are a lot of variables. But, those are the numbers my 98 Disco (4.0L) posted testing a CAI system, K&N filter, and hi performance chip. By the way, the change in torque numbers was minimal, also.

Just to keep you guys going -
wheel torque is the same, regardless of tire size.

"wheel torque is the same, regardless of tire size."

I don't recall anyone saying differently. Not trying to be a smartass, I'm just not sure where your coming from.

Maybe you're setting us up with a trick question? "Wheel" torque is the same no matter what the size of the tire and the same goes for engine torque. But, the torque applied back onto the axles, diff. gears, and the rest of the drive train increase with the size of the tire and it takes more torque (rpm's) from the engine to rotate the tire at the same speed as a smaller tire. Which puts more torque on a lug lug nut when you loosen it ... a 6" ratchet and socket, or an 18" long lug wrench? And when a cheater bar is added to the equation?

I knew that physics degree would come in handy some day. :-)

nah David, I just wanted to connect Thom's idea about what propels the vehicle with tire sizes. BTW, "torque applied back" is a bit of a jargon, too :-)

I put a Budweiser sticker on my old 96 Disco and instantly got 6 more horsepower! Big torquey Clidesdale horsepower too!

Oh, and FWIW...snorkle or not, you won't stay out of the dust/sand we had here last week. From the 6th floor of my buddies apartment we couldn't see the railing on his balcony!
