| ![]() @abhik- I did consider the boost controller, but backed out because there are no after market clutches for the Swift Diesel that I know of. No major power increase mods will be done till I know there is an alternative to the OEM clutch. Still hunting for an affordable intercooler. But first i have to get to MASS and open up the engine bay to take measurements of the stock intercooler |

| ![]() You bring up a good point, and I agree with you totally in principle. Boost lag sucks and we're not helping by adding plumbing for a FMIC. However, from what I've seen - top mount intercoolers don't really work. Heat soak really kills them. I have not worked on many TMICs but I did watch a Mazdaspeed 6 get dynoed, and it lost 30HP with every consecutive run due to heat soak. It literally went from 265 to 230 to 205 in consecutive runs with 20 second breaks. This was with some dry ice on the intercooler to help with cooling on a cool day - ~15*C. The only other car I've seen with a TMIC is the Subaru. Despite the huge scoop - most enthusiasts have found that a FMIC performs better. I will admit - these cars do have a bit of turbo lag, but they have a good excuse. With boost ranging from a stock 14 to 28psi modified, they make 300-550 HP at the crank with torque to match. Diesels rely on boost for power even more so than these cars do, so I think the tradeoff (boost lag for power) is worth it. Thats just a subjective opinion of course - the final call is for the owners to make. Ram Quote:

Ask people on the forum who have turbocharged their Swifts. | |

Senior - BHPian ![]() | ![]() What are you guys talking about? Have you seen the DDiS intercooler? It's FM to begin with, and pretty good at that. No need to change it unless you're looking at going +10 psi on the boost, by which time you're also going to need custom conrods. Will someone please explain to me, with a front-mounted turbo, how an FMIC has a lot more plumbing than a TMIC? |

I know Tata's have a rear high mounted turbo set-up which suits the TMIC with less plumbing. | |

Its on the right side, beside and slightly further from the grill than the radiator. I'm looking to upgrade the intercooler because the car struggles in hot weather. I thought that was due to the heat soak.right or wrong? BTW do you know what the stock boost is for the Swift? 8 psi is what I thought. I'm told that the tuning box does not change the boost levels directly, but read that the Pete'd Elantras were showing higher than stock boost with the tuning box.

Heat soak will be worse with a TMIC. Remember, hot air always rises UPWARDS. Hot air from the engine bay will rise upwards into the TMIC. All common-rails run around 1 bar, slightly above. Swift is about 15 psi and so is the Elantra. The Octavia 1.9 TDI is around 1 bar. | |

![]() I was thinking about a bigger Intercooler, and was wondering if there was space to install it in the stock location, hence the TMIC discussion started. So, do you think the performance drop in the afternoons that I experience currently will be controlled if I get an intercooler that has more surface area and made out of materials that have more favourable thermal characteristics? Especially, since I'm thinking of a boost controller to be added on in the future. when you say 15 psi- that will be 1Bar+15psi in absolute terms right? sorry for all the silly questions. Any suggestions from your side on the clutch? In case I need to replace it. currently, everything is fine on that front(touchwood) I did think of the convection effect heating up a TMIC, but thought, that should be solved with ventilation/hood scoops. | |

Senior - BHPian ![]() | ![]() I suggest you start by measuring the performance drop. Do 20-40 in 2nd and 40-100 in 4th runs at different times on different days, always shifting the same way, on the same road, and note down the time taken. That will give you an idea of the actual 'drop' in performance. My guess is it will be more perceived than actual. Though a cool night will see a definite and noticeable increase in performance. When someone mentions psi or bar on a modded engine, it is in terms of increased pressure. For absolute pressure, add 14.7 psi or 1 bar -- since you live at MSL. A bigger intercooler will also lead to a drop in boost, upto 5 psi depending on size, and an increase in lag as well. I doubt you can get a better material in the same price range. The DDiS intercooler is actually pretty good quality for the price. Clutch you will need to go custom, in which case you're looking at over 25k, excluding the flywheel. If the DDiS runs a dual mass flywheel, your clutch costing has now doubled to 50k. You could experiment with the Linea VGT clutch, and I'm sure the 1.6 120 bhp MJD abroad must use a better clutch and similar gearbox. Think logically, a heat scoop will never solve a TMIC heatsink problem. There are no silly questions. But you may want to take all my words with a bucketload of salt. Quote:

BHPian ![]() | ![]() I thought the Linea only came out with the 1.3L MJD with VGT instead of the FGT and thus 90BHP? I would'nt really call the Indica TMIC Intake as RAM Air Intake as the the outlet is fairly hidden beneath the chrome strip in the grill. But the idea is good. Though after reading the above posts i think it still would get a fair amount of heat as an air-scoop on the bonnet is also absent. @atlblkz06 @v1p3r How do you think Subaru manages the TMIC set-up w.r.t heat soak from the engine? I have just seen a Subaru from its exterior and never managed to get a glimps of the engine bay. There is just 1 Impreza in Delhi that i know of, painted in WRC graphics. The above disscussion made me very inquisitive about how Subaru manages their TMIC since they run the same for their rally cars. Last edited by Rehaan : 21st February 2009 at 12:03.

Senior - BHPian ![]() | ![]() i think nikhil was talking of something other than the scoop on the TCIC indica. his was a NA indica with some good engine mods |

Senior - BHPian ![]() | ![]() Arrey Dr. Ripper !! U already have petes. Why are u wacking your brains so much to get more bhp from a quite efficient 1.3 DDis...? Want more power in a hatch ? Get a Getz or plonk a 1.5CRDi in your Swift.... ![]() |
