Lexus SC430 :: Simplest Upgrades To Increase Torque / HP?

I recently got an 02 Sc430, it is completely stock, color is Egyptian Sand Pearl. I'm wanting to add a little HP and torque. What are the simplest upgrades I can make to increase the torque/ HP? Also, I would like to put the newer Sc430 tail lights on it.

Prius (Gen 3) :: Angular Torque Method Is More Accurate Than Standard Torque Wrench

During my 35 years of experience as a production line and service engineer in the aerospace industry, it was my job to determine the least expensive and easiest foolproof way to perform any production and service operation.

Many readers here have related their experience with the oil filter housing and their difficulty with its removal and reinstallation with the need of a torque wrench to correctly tighten it. Most all technical tightening of screw systems have gone to the "angular torque method," as it is more accurate than the standard torque wrench.

Golf/GTI VI :: Possible Causes Of Increase In Fuel Economy

Wondering what could cause an increase in fuel economy. My GTI has been running at 29 +/- MPG since the day I bought it, but no higher than 30. I took it out for a ride on Sunday after I changed the front brakes Saturday. The dash tells me it's running at 34. So I filled it up and manually clocked it on a 50 mile trip. I refilled at the exact same pump - just to remove any error. And what I calculated is that the computer is right.

There is no loss of power. However, I've been fighting intermittent misfires on cyl #1 and #2. the misfire on #1 has all but gone away after finding out the coil wasn't sitting right and the spark had loosened up. I've tracked #2 down to either the injector or carbon. I'll be taking care of that next weekend.

Golf V R32 :: Rotational Vibration At Front Right Increase With Speed

I'm hoping to see if there is another solution here. I just hit 100k on my .:R and it has developed a vibration that increase with speed front right. I have done a few things already including the following: swapped out winter wheels for summer, had summer wheels re-balanced (both are hub centric). Both lower control arm bushings on L&R side (both were original), new ball joint front right (it was wiped), new hub assembly/wheel bearing front right, re-torqued all the sub frame bolts to spec, inspected tie rod end - appears OK, inspected strut mount - appears OK, strut and coil appear OK, neither CV boot is not torn. replacing the wheel bearing made it quieter but the vibration is still there. It feels like the worst possible unbalanced wheel and the vibration is exaggerated under a load. I'd try a CV next but I'm having a hard time sourcing a front right CV.

Golf/GTI VI :: Turbo Sounds Much Meaner / Significant Increase In Throttle Response

I just installed the BSH turbo inlet pipe as well as the Neuspeed P-Flo intake.

Install was pretty simple, the only things that gave me trouble were those stupid clamps on the inlet of the turbo and on the maf, just because they are a pain in to get off ..but anyway im very impressed with it so far. It looks great and high quality. It sounds amazing! Not too loud that it gets annoying, but still gives that p hhhhh sssss sound that everyone loves.. The turbo sounds much meaner and there seems to be a significant increase in throttle response. At first i didnt really notice much power gains, but after driving it for about two days, i've noticed that my top end is a lot better and it pulls alot harder on the freeway and in 6th gear.

I also installed the forge diverter valve yesterday and like everyone says, its not much louder than with the stock diverter but it did gave the intake more of a flutter sound.

Golf V R32 :: Squeaking Noise From Passenger Side Increase And Decrease With Engine RPM

Symptoms : You will hear a squeaking noise from the passenger side of the car. It will increase and decrease with engine RPM, and apparently can be heard from inside the car as well. This noise is from the tensioner bearings failing...which, if gone untreated, will then cause the serpentine belt to fail.

If the belt fails, it seems that the battery light will come on, followed by engine coolant temperature spike (overheat).

Bad tensioner sound:

Confirmed failure shortly after this sound:

Golf/GTI VI :: Trans Not Going Into Third With A Lot Of Torque

Yesterday leaving a meeting, I started it off gunning it from a light and i went from 1st to 2nd and foreshore i placed it in 3rd and some how it went into 1st and it happened twice last night. i have the forge short shifter from going north to south and from west to east. I been driving stick for years and never had this happen to me, maybe if it happened once it was a drivers error but it happened twice in one night. I have stock motor mounts and even before this my car when gunning on it it won't go into third gear so ill end up missing. And since it hit 8000 rpms do u think I did sum damage to the vehicle, it drives fine and no abnormal noise. anything to check for?

Golf V R32 :: Turbo Idles Then Stalls - Loud Backfire When Started To Increase Throttle

I have a mkv r32 turbo. It had C2 910cc software, car ran great. I had to change to UM 870cc software and injectors in order to get UM dsg stage 3 tune. I had it out for test ride, ran nicely for 2 miles. Then i started to increase throttle, a loud back fire, so i pulled over. It stalled, i restarted it, ran for about 5 secs at 14.5 afr, then sputtered to 10s afr, the stalled out completely.

Had it towed home, all 6 plugs were black. VCSD mobile log states multiple misfire and misfire #6. I put new plugs and switched coil packs, same issue.

Golf IV R32 :: Loss Of Power And Torque Especially After 3 - 4k Rpm

The car has 108k I bought it with 101k that being said I had no clue when the last tune up was or if the coils were replaced, now I did replace the transmission, transfer case and clutch since then I've noticed a loss of power and torque especially after 3-4k rpm car just seems to fall on its face, if I had to explain it I would say it feels like it went from being tuned to stock, I have no clue if the car had software or not. also some times I get a sputter or almost a hesitation from the rear, I have done the haldex service 2 weeks ago, It absolutely feels like the car isn't breathing right I don't hear the intake as much or cleanly I'm wondering if the intake manifold bushings are bad and could even cause this? doesn't seem to pull as much just from the start though I used to just drive normal and the car almost felt like it was pulling its self doesn't feel anywhere as quick.

Golf V R32 :: Horrible Dip In Torque And Power After 4000 Rpm

I have an my 2008 Golf mk5 R32 DSG. I have fitted the GruppeM Intake , done the decat and fitted a Milltek Resonated system. I am based around 1.12 miles above sea level and our fuel here is probably the equivalent of your 91. I had the car dyno'd yesterday with the graph below :

1. What is causing the horrible dip in torque and power just after 4000rpm? Do R32 graphs general look like this? Could it be a result of the variable valve timing?

2. I have a feeling my DSG's mechatronics unit is faulty , could that cause a loss in power or have a result on the dyno run?

3. The power does look low but if I convert it to coastal power it looks to be around 150wkw and 300Nm which seems right?

The biggest concern is the dip in the graph ... Power was measured at all 4 wheels ...

Golf/GTI VI :: Installed BFI Torque Arm Insert - Huge Vibration With Windows Up

I just installed Black Forest Industries Torque Arm insert for the 09+ TSI (He said TDI's work too). Anyways the vibration noise is unbearable with the windows up, it is producing this sound frequency/ pressure that gives you an instant migraine. I am a mechanic and I followed the instructions. You really can not keep the car at idle or you head will explode. If you bring the rpm's up to 1000 its all good as gravy.
