Does a heat shield makes a huge difference for a turbo car? watch this video below

Does not, so better lead your pod out of the engine.....hahhahhahahah:rofl:

I thought Parada Spec 2 is somewhere like in Extreme or Max because of its thread design. Like something comparable to R1R, Direzza Star Spec... But now it seems that it is only like on par with ATR Sport.

If FWD, then your front will raise up when you accelerate hard in 1st gear? And is there such thing as torque steer as I have heard from many about high powered FWD cars. Not so sure what is torque steer. Difficult to steer during high speeds?
Don't judge a book by it's cover....hhahhahaha
Same when I change from Goodyear F1 GS-D3 to F1 Asy, Asy looks so mild whereas D3 was so fierce but then Asy did prove to excel in it's performance over D3.

Torque steer is the pull of the steering during hard acceleration. If have uneven drive shaft length, power to short shaft will have more power, therefore steering will pull towards the shorter length side. Main thing when driving Turbo FWD is when you are at a junction. Steering turn to go left or right. If you do hard acceleration it pulls to where your steering is pointing, you will have no time to steer back straight.....hhahhahahhah:rofl:

Just like Michelin PS3. Thread looks like normal tyres but actually it is gripping.

So this torque steer thing usually happens in turbo FWD because their torque is high? NA FWD should be fine even for cars like modded K20A? Need accelerate slowly when going out of junction then...

But even on the straights if uneven length drive shaft can happen to pull to one side also....

Then how to solve this problem? Can use LSD or not?
Seen on some cars they have a link on the long side, then from link to wheel is same as the short side. I think it works but not sure.
To solve big torque and power go 4WD.....hhahhahahaha:biggrin:

I do read them but do not take fully what is posted. Weather difference, type of road, cars, etc...
That is why local forums are good too, but take in all postings as a whole. There are bound to have positives and negatives, but then one with more positives will show that, that one should be better....:biggrin:

Our hot and humid weather might have different impact on tyre performance and lifespan since they are made out of rubber...

That is why here more summer tyres and there all seasons tyres, unless you use summer tyres then switch to winter tyres....:driver:

Japan basically the same, but what gets imported in are summer and all seasons tyres. Winter tyres of no use here....:smokin:
Winter tyres are those studded tyres right? Some of them looked rather narrow instead of wide. I saw before at magazine. Or maybe those are for snowy terrain?

Nope, studded tyres more for mud and off road. Winter tyres many many sipes to help grip.
Here...

Does look quite unique unlike what we normally see over here. And the width of the tyre is rather thin as well. Wide tyres are not suitable in winter I guess?

I thought winter tyres are something thin and narrow like this...
Is the same as driving in heavy rain, narrow tyres cut through water and same as in heavy snow, but if normal snow normal tyres are okay. Wider also more contact surface. There will always be pros and cons on everything.

Another thing is I post as normal or original tyre size. If you want to go narrow you have to down size means changing to smaller size rims, higher profile tyres, just like here when we up size we go the other way. So will be more cost, so best just keep to original size.

Anyway, no point we discuss this as we do not have snow here or are you going to migrate.....hhahhahahhahaha

Some reading for you....

Sorry for the off topic, just installed a walbro fuel pump for my bolt on turbo myvi, is a fuel regulator required? Car is still stationary in workshop, and im wondering do I need to install a fuel regulator before going to dyno and tune(e-manage)

currently stock internals, and YRV injectors.

regarding the tyres, i think i will go for AD08R instead of PS3

Your fuel system is return system? If yes, can fit the fuel pressure regulator

I thought suppose to look sleeper now fit Advan Neova AD-08R.....wah!:driver:
But for extreme tyre be careful during rain time...:smokin:
