Turbo Timer

[raptornexus]

Hi i was thinking of fitting a turbo timer to my mk1 octy vrs,and was wondering if anyone on here has done it,or if there is a guide anywhere..many thanks.

[mannyo]

I dont think anybody bothers as on the vRS its not really that necessary, if you go for a blast then simply drive less agressively for the last couple of miles. My old remapped vRS was fine and it was used for trackdays and lapping the nurburging, despite all of this after 4 years the turbo was still like new.

Fitting one will mean bypassing the imobilser therefore invalidating the thatcham cat 1 rating and affecting insurance as a result.

Yes its easy but not as trivial as on some japanese cars. you need a relay to bypass the immobiliser and enable remote locking while the engine is still running.

I used this guide to install in a Mk.1 Seat Leon 1.8T and the instructions were accurate, I'm sure the Mk.1 Octavia would be the same.

also invalidates your insurance and is completly pointless on a turbo that use both oil and coolant to cool

I don't know why people get so upset about others installing turbo timers. I've seen this on many forums. Someone asks how to install a turbo timer and gets a deluge of replies on why he doesn't need it.

The advantages of letting a car run for a while are obvious - keeping the coolant and oil running through the turbo and engine reduces abrupt thermal expansion/contraction cycles.

mannyo, if you follow the guide the car will lock, the immobiliser will arm, and the car cannot be driven off if you engage the steering lock and install the handbrake wire correctly (shut off engine if handbrake is lowered). If you have any questions let me know.

When you turn off the car both the oil and water pumps stop as they are driven by the crank. Using a turbo timer allows water and oil to circulate for a while keeping the temperatures down.

And about insurance even remapping the car without declaring would invalidate insurance.

but due to the cooling on these small kkk turbos the need for a turbo timer is none as if you drive the last minute of your journey normal it will be cool

and again you will have no insurance ( remap not decleared the only people that do that are stupid end of)

I don't want to argue about this, my point is while you may believe it to be unnecessary, there's no harm in it.

and I mean no offence by this but what do you mean "remap not decleared the only people that do that are stupid end of"?

if you mod your car but dont declare the mods then

1 you are stupid

2 you cant afford to pay insurance dont mod it simple

Does a turbo timer have to be declared? car is not at any higher risk of being stolen

[mannyo]

of course it does, to fit it you need to bypass the imobiliser by fitting a relay thus giving the potential thief a way to start the car without the appropriate key. As mentioned fitting one will invalidate the thatcham rating of the the oem immobiliser and any alarm fitted.

So a thief see a car with engine running and no-one in it. Surely that becomes a higher risk before he even trys to get in.

Not more than once anyway. Chop!

there is a small water pump for the turbo that runs after shutdown anyway so no real need for a turbo timer

Is There??

[Guest westallc]

where is this water pump then ???? or is it to small to see

if u put a tax disc holder in your car,thats a modification,bet you dont tell insurance then?at the end of the day you say you bought it like it,then they have to prove you modded it,which they cant... simple

Oh is that right...Mmmmm..Don't think so.

i've got an hks turbo timer for sale which ive taken out of my octavia vrs as it was never fitted due to havin to mess with the immob and being told by a subaru specialist that there not needed unless your flat out and then decide you need to switch the engine off. otherwise by the time you've had your fun thrashing about at full revs, you will have to drive at a normal speed before reaching home so the turbo will have cooled so no need for a timer

I think in general terms of telling the insurance company about mods, it is when you change parts of the car to change it from is factory capabilities, such as:

- bigger turbo (it can go faster)

- different engine map (it can go faster)

- bigger brakes (it can stop quicker, thus in the insurance companies mind, you will be driving faster)

- change of shocks from standard (you might be driving the car in a more aggressive manner)

Adding a tax disk holder does not really fall into that category.

Changing the stereo does not really adjust the performance of the car, but might cause it to get broken into more - unless you sticks in an expensive stereo I guess they don't need to know.

Anyway, I'll climb back into my box, as this topic seems to have gone off on a slight tangent to that of turbo timers

whats the need to bypass the immob.. it only sends a start signal to the ecu, if you were able to remove the key and keep the engine running (say by adding a wire under the dash) it will keep running even tho the chip is no longer near the reader.

should be no need to bypass the immob at all unless you are after remote start.

it also takes more thasn 2 miles to cool the turbo as i had mine still glowing after 2 steady miles and wouldn't want to stop the flow of coolant with it that hot..

i think older volvo turbo's had a small electric water pump to circulate coolant after switch off for 3 mins due to heatsoak into the cyl head from the turbo.

First bit of sense I've seen in this thread.

There is an electric auxiliary water pump on the 225 model 1.8T's (BAM etc..), not the 180 engines that came in the Mk.1 VRS (AUM or AUQ), but it pumps much less than the crank-driven water pump.

Also, even if there is an electric water pump fitted, the oil is not circulating as the oil pump stops.

Anyway, I meant "bypass the immobiliser" in laymen's terms. You are correct, but there is a circuit (CCM or something like that) that needs to be bypassed to allow the remote lock to function as normal without the key in the cylinder. It is covered in the instructions I posted.It is the same circuit that disables the remote buttons while the key is in the holder. Other cars don't have this anyway so I see no harm in bypassing it - I've had a BMW where the remote buttons work while the key is in the ignition.

Driving a mile or so down your road slowly may reduce turbo speeds, but it will NOT cool the turbo enough. Also the argument that "the kkk turbo is small" is irrelevant - small turbos heat up and need cooling as much as bigger ones, especially on remapped cars.

It is right and i know so

[Kenny R]

A tax disc on your windscreen is NOT a modification you need to inform your insurance about,but any other modification whether to performance,or purely cosmetic IS.If you do not inform them off any mod they can and will prove is not standard (including re maps) and will refuse any payout,trust me.

So back to topic if you do fit a turbo timer (which isn't really required),and leave the engine running,with the imoboliser bypassed,I think your insurance would be very interested.
