Look out for newage 17's with 225/45 RE070 Bridgestones already fitted. Great choice for track work. Will need rear arches rolling if they're not already.

Gerry - can you tell me what tool is needed to remove the 99/00 MAF? It's a hex type head with a 'pip' in the middle so an ordinary hex key won't fit :roll:

ok so the plan is to get/install/replace the following prior to my next track day:-

Oil pressure gauge and sender
Water temp gauge and sender
Egt temp gauge and sender
triple gauge mount for centre consol to hold them all
Knock sensor- not sure where to put it yet but thats another issue)
New hybrid fmic core to replace the HKS one
Move the air filter into the inner wing( any idea's on whether i should look at removing one of the front fogs and having an inlet in the air filter if so how/which kit etc?)
Replace the current simota breather with a return to sump oil breather kit
going to look into the catflap sump but not sure if its a necessity and how much they are etc.

Any idea's/recomendations on the above will be more than welcome. Also interested in any info on the datalogic software etc. As being able to run E85 will also help with the temp issues etc.

Once everything is installed then Im going to not come in when it hits 105 but stay out and monitor everything to see if it goes up much beyond 105. Ive been reliably informed that oil pressure could be more if a concern above 105. But well see etc.

Im now booked for the sundays to quote gerry"chasing cones around an airfield" scoobysprint so I am trying to use the car as well :wink:

You don't need water temp guage or Knock sendisplay. The Apexi commander will display both. Read the foregoing posts.

What's wrong with the HKS FMIC?

The Simota air inlet with flexi pipe from the front fog would be my choice. Similar to the Powerflow Cobra (?) or whatever it's called.

Does your car kick out oil from the breathers? Some do, some don't so you may not need fancy return to sump breathers. To start off, run three pipes frome the breathers into a coke bottle and see what it catches, then decide what you need.

It's unlikely that you'll need any cat-flap sump plates yet. What power are you running?

More money than sense springs to mind but that may be unfair :)

> triple gauge mount for centre consol to hold them all

Yup. Unfortunately the 52mm gauges are slightly bigger than DIN, but I've managed to fit a DIN plate (from Nick at gaugeplace) in there in the past with a bit of careful cutting.

> Knock sensor- not sure where to put it yet but thats another issue)

Detalarm from Gerry if he's got some. Neat box that can sit on top of steering column. Or remote LED version with LEDs sunk into binnacle just above speedo for a really neat install.

> New hybrid fmic core to replace the HKS one

What's wrong with it? Pressure drop, or cooling effectiveness? I got a charge temperature gauge from Zak back when I had a TMIC and reused it on my Hybrid FMIC, so I can see the big difference it has in cooling. Harvey in Darlington is yer man for Hybrid FMIC.

> Move the air filter into the inner wing

May cause issues of its own if not done carefully (water ingress). I'd get a charge temp gauge and take it from there. Maybe heat-shield the filter and fit a miniscoop, but not convinced its necessary. I have v.stable charge temps without any of that.

> going to look into the catflap sump but not sure if its a necessity and how much they are etc.

Cosworth plate is about 150.

Ah, you'll be running against John Felstead in his newage scoob (black one I think). He's had several classics, has loads of track experience, is a racecar engineer, very knowledgeable bloke.

Yup. Is your Apexi already programmed to flash the CEL at a given knock level? Easy to do and gives you an immediate warning, whereas you're not going to be looking at hand commander knock display at the instant you get knock. But, get familiar with typical 'knock' level for your engine ie. the typical numbers on the commander which represent background mechanical noise not det.

oil temps not a problem....
I regularly ran higher than 105 on track.. wouldn't get much above 110 though...
I found that mine was fitted behind teh front grill and removing this on track was sufficient to increase air flow and reduce temps.

Air filter in the wing (first done by Zak on my car), has issues in the wet. Mke sure you keep wheel arch liners etc in place else water ingress is a slight issue. will help with charge temps

Regarding the Simtek, i have to echo what Gerry said. there are only a two poeple i would get to map a simtek.. Simon - Jolly Green Monster or Steve Simpson. trust me this is from personal experience and those of other friends.

Unless you running R888's i would doubt you would push the sump too hard. I ran a standard car for a couple of years with around 6 track days a year and never had an issue,

HKS is not the best intercooler but would be OK for your current power levels. Would suggest changing if you push teh power further. I ran the HKS on mine at 430Bhp and in competion. TBH the charge temos were OK when running, but the heat soke on the transponder gave false readings when you come in to the pits.

Above all i have to agree with what Gerry and others have advised.

No money and no sense is closer to the mark Gerry.

On the flashing CEL I now know why on 2 or 3 occassions the cel has flashed down the straight on a couple of events. Its not done it consistently just one brief flash.

On the fmic a few have commented on its not that efficient and id be better of with a hybrid core. If this isnt the case im more than happy not to have to spend any money etc.

Re the breather the car doesnt use any oil etc but TSL,mocom and scoobyclinic all said its not great and could be restricting oil flow which may be adding to my oil temp issues.

TSL in particular suggested moving the air filter but most people have suggested the same thing.

As I said whilst ive been around scoobs,evo's etc for a long time Im a complete novice in most of this as this is the first true track car ive owned and its all just a wee bit daunting and dont want it to go horribly wrong and not be able to carry on etc. This is why I want everything to be spot on as id rather spend a bit to save a lot etc.

The commander sits in its holder in the glove box and I dont go near it for fear of screwing the map up etc. Guess im gonna have to get a bit braver :oops:

The HKS is restrictive, but i'm not sure that it would be a big issue for your current power levels.
HKS themselves will state that its a 400BHP FMIC.
