I think well-designed tanks are quite safe. I figured you just wouldn't like to lose your trunk space to a propane tank. If you're married, I'm sure your wife will glare at you every time you go shopping lol.

I think an upgraded intercooler might be one of the best mods for Indian diesels given the high ambient temps as you noted. Along with chipping the car and possibly working on the exhaust, this will probably be a worth upgrade. Do you know what your IAT (Intake Air Temp) looks like? About the exhaust - I guess not many turbo-back exhaust systems are available? The market is still in it's infancy though - things will only get better!

Hmm I dont have any direct links, but googling is always fun! The diesel market is very very small, so take a look at european car forums. You might get a lot more information there.

Plus the exhaust note is going to be horrible.
And if the headers are not re-designed accurately then quite a few things will go for a toss...:-D |
Well the point is to reduce any back-pressure from the turbo-back, so we're not messing with the headers. How much this will help really depends on how restrictive the exhaust is. I'm used to seeing 4-5" exhaust on diesels because they're all 5.9 - 7.3L engines so I dont know what size you'd need for a car. They all sound damn good though (to my twisted ears). Then again I think my car sounds good, and my sister tells me she can hear my car from 1/4 mile away, and when I pull into the garage the house vibrates from the near straight-pipe exhaust
I'm really waiting for some "Fast and Furious" type of movie to hit Bollywood. I'm sure boosting cars will gain mainstream acceptance and the market will change. In the US, Holley's sales apparently shot up by several hundred % points after the first F&F movie was released. (They own the NOS trademark) Unfortunately this will also sharply increase the number of dumbasses on the road trying to show off in their riced out cars, but thats life I guess.
