Top Speeds of a 4x4 (pure offroaders)

Manuuj · 18th September 2009, 13:40

Just a shade over 200 kmph on arrow straight rajasthan roads in a 3.6 TDV8 Range Rover.

Kandisa · 18th September 2009, 15:17

Here is my part. MM440 with 1.8 Isuzu: Absolutely effortless & comfortable in 60-75 range. Didn't dare to go beyond 80 (that too on DND) so far, though it should be capable of more.

GauravG84 · 18th September 2009, 19:51

I have done a 155 kph (95 mph) in my Jeep Wrangler TJ. It wasnt very comfortable because of the wind noise due to the soft top, however the jeep stayed pretty stable at that speed.

I was doing around 4500 rpm so not even redlining.

This was with a stock engine - 4 litre Inline 6
The only addons are an Xdi Air Intake, a Walker Cat-con and a Dynomax Cat-back. Thats it.

Planning some engine mods soon.

- A supercharger or a Turbo Charger
- Performance chip

etc. will upload pics

Gaurav

My MM540 used to do 110-120 kph in it's initial years. The handling was okay for the first 10000kms.Now after doing 165000 k, it max out to 85kmph and also the suspension won't let you to go above that.

Jack 33,
Thats a serious drop in performance. 165000 kms on a 2.1 is a feat in itself. May be its time to overhaul it. If you feel your engine is still healthy then check the speedo cable. If it is cut then it shows less speed. This happened to me. My jee[ used to show 70 kmph top speed. When i changed the cable it crossed 90 kmph with lot of reserve power.

Yes Vinod, there is a serious power drop and with the new Apollo bullet tyres it's not moving at all.I was thinking of doing an injector cleaning plus pump calibration before going for a rebuild.
@Shanawas, Only if those bangalore Kings are not there.Hey,we had an OTR yesterday in Munnar with lot of fun and casualties.It was raining heavily and you can imagine how good the track would be.!!!

Jack33,
Those Apollo bullets are giving a good workout to 2.5 litre engines and harjeevs maxes out at 85-90 kmph, your jeep engine is still a poor little soul in comparison which served you beyond its life. Do as planned as it might just bring back that engine to life for few thousand more kms!

Please post pictures of the OTR you guys had. Kerela jeepers are one crazy lot, iam sure you guys would have had fun. Whats the casuality all about?

Hey Guys,

Query:

My 550 is being ready this week. I have not tested it for Speed yet. I have got XD3P engine 99 model Army Spec. I am using it on 31inch tall JK Sand Cum Highway tyres (Brand New) . Engine , alternator,starter , Brakes, axels, mechanicals fully overhauled and FIP caliberated newly. Putting new Steering wheel either original 550 or from Bolero.

What top speed can I expect from it? What should be decent speed on highways? I generally travel 550kms to and come back to my native I have not tested it on highway though.

It should be capable of doing a decent 70 to 80kmph on the highway. Top speed done on the same was 120kmph.

What is the maximum speed you can go in a gypsy king mpfi with 4wd engaged?

On the highway? I don't know how fast you can go, but I can tell where you will be going. To the garage with cracked driveline.

@Samurai - Could you please elaborate on your statement?

Why do you thinking driving fast with 4WD engaged would break anything?

Is the statement just specific to Gypsy?

I have a 4Runner 4WD and when ever it rains or snows i engage the 4WD and have many times done upto 80 Miles per hour with no issues what so ever.

It is applicable to any 4WD vehicle without center limited slip differential.

Your 4Runner has center limited slip differential. So, you can do it without worry.

Tarkesh, it actually depend upon what tail and crown ratio (also called differntial ratio) being used. My 1990 model originally had 8 tail and 43 crown (ratio 5.38) which initially I changed to 13:46 (ratio 3.54) but having problems on sand driving. Finally I am running on 11:47 (ratio 4.27) and happy with overall (highway + offroad) performance.

My Jeep has 31 inch tall tyres (31x10.5 R 15) and I have not yet checked the maximum speed but it easily touches 100 KM/Hr (the speedometer error already ractified).
