Forums Forums Enthusiast Forums A - Z Autowirral The Scooby Is Dead :(

Sorry to hear about the scoob!

If you want somethin fast/reliable/goodlooks/different/potential
you need a SKODA! lol

At that speed and gear it would have been boosting at approx 16 p.s.i.

At that rpm the supply and demand of the engine is very high, and ACT temps will have been very high

Did it "drop off" to 16psi?

What boost do they run @when standard ?? water injection is very good if running high boost as it helps keep intake temp's down . Any turbo car can suffer from melted pistons when the boost is turned up . A m8 of mine has just lost a piston on his rs4 , it's running 495 bhp , that was down 2 a faulty injector!!!!!! £13000 for a new motor so he's getting a set of pistons from germany,
will phone a m8 who rebuilds scooby motors to see if he's got any think for you???

Does ACT stand for what i think it stands for, Air charge temp?

This is a very informative topic this.

I believe it is ur engine runnin hot mate.
Youve got a 400BHP engine running underneath ur intercooler wafting it with hot air,this is stoppin ur intercooler doin its job and ur charge temp is well high. I think u need a more efficient 'cooler.U can do this by
a/getting a front mounted intercooler,thus only cooling ur charge air as its nowhere near the hot engine
b/Increasing the size of ur scoop to drown the cooler and engine with cold air
c/water injection

Up to u mate but it definately needs it,ive not seen many 300+ BHP cars still runnin stock 'coolers
Most sooped up cossies run massive coolers and ive even seen a 350bhp+ one that had its bonnet lifted at the back a couple of inches to aid cooling.

Isnt there some sort of thing u can do with nitrous to cool ur charge air??

A cossie I/C and a Trust I/C cool at the same rate and temp according to the tests they've run. Identical

Cheers Grizz, much appreciated matey. They run approx 12 - 14 p.s.i. as standard.

ACT does stand for Air Charge Temperature

I was not running nitrous at the time so i was only pushing approx 300bhp.

If it is a melted piston then obviously it is down to heat. You can either use a water spray on the intercooler to cool the charge down or nitrous/Co2 to spray onto the intercooler to cool the cool the charge down. The nitrous or Co2 are expensive, especially nitrous but allot more effective. Water is free but not as effective.

I have been looking at a front mount intercooler but any decent one costs £1500

Sorry to hear about the Impreza.

This has happened with me. I came onto the M53, belted it in 2nd, next thing the rear view mirror is full of white smoke. The head gasket went! Truly horrible feeling.

Dont u have a porsche? hmmmmm
Modded porsche *drools*

Maybe keep the scoob as a show car and pimp the porsche(or if u dont have a porsche pimp somethin else)

Lol at Scoop, I did have a Porsche before the impreza matey

just phoned my m8 he's got a set of sti version 5 pistons , just about the best you can get , will let me have them for £400 , sti head gaskets are £160+vat ( steel )he will lend me the tools to change them if you want . grizz

Are they new or used

I am going to have to wait until i hear about the warranty on my current engine before i can decide whats going to happen

GGS2500 : 2.5 Litre Subaru Short Engine

Only heard about what happened tonight. Gutted for ya scoob.
That 2.5 conversion looks monsterous and if Subaru don't pull through I reckon you go for it.
Maybe you should get another car as a daily driver, something cheap to buy and run that'll stay on the road.

Hmmmm.... I have the CW van, 2 other cars to smoke around and my Fireblade dont forget.

Lets see what happens with the warranty first.

Scooby, you can get huge FMICs very very cheap, its the fitting that you would have the problem with.

A decent sized cooler, say 300mm x 600mm x 70mm can be had for about £200, and then you just need to find someone who can make the hard pipes to fit it all in - this will certainly help with your intake temps. A FMIC is one of the first things Ive fitted to all my 200's as a matter of safety, and Ive also fitted an ACT gauge so I know how hot the air going in to the throttle body is. On both cars with a similar sized cooler to that mentioned above, even flat out on the motorway on summer days I dont think I ever saw the temp exceed 40C
