still not enough to keep up

hows things?

David

wrrjones

Hi David
how you mean keep up ...lol....

i am trying...

.......... chris

p.s there are some bitts ive missed out .....

wrrjones

there will be more to come ... and a lot of boost ....


chris

M0NEY

Sounds good mate - keep up posted.

I take it anti lag with the motec

You got 18s - i think you need bigger momma discs

wrrjones

yup and launch control..... yummy........ chris

tweenierob

I think this one will be ready around the same time as mine, is going to be interesting to see how they vary as we have almost the same spec except two vital ingredients

Chalk n cheese
Fast n Slow

Launch control was fun, shame it was wet when we set it up.. It is much more fun going in a straight line when launching

Some interesting stuff on both our cars that are available at a high premium at present, but watch this space...

here is a pic of the scoob with the FMIC and bumper trail fitted new on in garage once everything is right....

You may need a bigger intercooler!

RB5SCOTT

Here's the APS one, its about as big as you can go on an 01 without too much hassle

tweenierob

What do you think of this one then


Rob.

RB5SCOTT

May struggle for big power

tweenierob

Be interesting to compare flow rates, no escaping the cooling properties of the APS.

Rob

wrrjones

cooling rates are not a problem there is a plan afoot to solve that.....chris

RB5SCOTT

What

Cold weather?
CO2= don't last long?
Water injection= not to be used to reduce inlet temps?

Is'nt about the pressure the intercooler uses aswell though?????

tweenierob

RB5SCOTT

Reducing pressure drop!

Not so sure why you'd need an intercooler the size of the APS. The Greddy one looks more than adequate.... have you seen the size of the intercooler than the Norris Evo (inexcess of 700bhp)uses? People seem to be obsessed with the bigger the better..... the WRC cars don't have a massive intercooler (yes they only run 300bhp ish but they have to get rid of a huge amount of heat due to the restrictor meaning the level of boost they run is *quite* high. Have you seen the size of the old turbo F1 cars intercoolers (1800bhp). Plus there's the arguement that the ideal intake temp is 40degC etc etc.

All IMHO.

I'd look at somehow 'boxing in' the intercooler so the air doesn't just take the easiest path... i.e around it.

Also why do you say water injection is not to be used to reduce inlet temps.... not sure everybody would agree with this. It's mostly used to get det at bay but i wouldn't say it doesn't contribute to charge air cooling.

tweenierob

Took the words out of my mouth...

WI is going to be used to keep charge temps down and cylinder temps slightly lower.

As of Saturday, is Chris's Car the only 2.5lt powered Bugeye in the UK so far??

The APS site 'appears' to sell the intercooler almost purely on its cooling merits, it does say that pressure drop is what makes a good intercooler but doesnt state how good the APS one is compared to other cores (size rather than brand).

RB5SCOTT

No

The WRC Impreza i/c is massive!

WI is not used to decrease inlet temps but cylinder temps/det. If you have high inlet temps you would'nt use wi to reduce it! Ask Pat or any other Mapper wi reduces inlet temps by about 4degrees, hardly worth it i think

Scott... have you read this:

Water injection... good or bad on 22b.com

If not i'd give it a good read. Ford's strategy (may not be the case now.... Ahmed describes the system he designed) was to cool the charge air not the in cylinder temps. Mike Rainbird also describes how his system would control inlet temps to 40degC but with the water injection turned off this would rise to over 60degC. Bit more than 4 degC . Most of the other WRC teams strategies would be to control det.... and i would say most people would use it for this purpose (Aquamist's Richard would confirm this), me included. But to dismiss it as an aid to cool the intake charge would be a mistake. It could be the difference between going for a FMIC for some people.

Either way i'd say that you'd need to look at your own individual intake temps to see what you need. For the cost of about £40 for a couple of thermocouples it's well worth it. People just seem to stick the biggest intercooler on they can find without knowing what sort of temp decrease they need (40degC being a good temp to aim for). Out of interest Scott what were your intake temps before you decided you needed that size of intercooler and what are they now?

Tony.

RB5SCOTT

I have a K-Type in my inlet already

My inlet temps were about 40degrees on the wrx top mount with 300bhp and as i was going for a bigger turbo i decided to go for the front mount. At 400bhp it runs at ambient on a cruise and never seen above 45degrees on a hard run for about 10minutes.

Fair enough if wi cools inlets by huge amount but primarily i would'nt use it to cool inlet temps!

Sounds like the APS does it's job very well, which i wouldn't be surprised at by the size of it! From what i've read from the states the Greddy and particularly the Apexi get just as good results tho from a far smaller core. I do like the APS myself but im on a pre bugeye car.

So basically what i'm saying is just don't underestimate an intercooler because of the size of it's core. There are far more things that influence it's performance than that. Chris has a Greddy now so let him see what results he gets whithout telling him he needs to change it already..... if it does become the limiting factor for 500bhp then furry muff.

Tony.

P.s i got basically a 4degC drop in inlet temps from a water spray system nevermind water injection!!

RB5SCOTT

Sorted then

Just offering my views If it works well then don't knock it I just think if you want real big power at 500+ then a bigger one is needed, mind you it sounds like Chris has a secret weapon in place

Scott

btw, My i/c is only rated to about 450bhp

Tone Loc

iTrader: (1)

Interesting it's only rated to 450bhp... is this a rating by APS? Harvey's made a nice 585bhp on a classic APS which is a fair bit smaller than yours iirc. Wounder what they are rated to by APS? Anybody know?

Tony.

RB5SCOTT

Sorry, 300-500bhp. thats what APS claim, but i'm sure it will go alot higher

wrrjones

we do have a nother option lined up if the FMIC dont live up to the flow that we require . like i said on the cooling side we have some options we will be fitting water injection as all the WRC teams cant be wrong . we have also allowed for slightly more heat in the build to allow us to run quite high boost levels.but we will se how things go might be good might be bad might go bang when we push it but i have a spare in case that happens lol.....

The Fixer

Just a point to note between the APS DR500 Intercooler and the DR650 Intercooler. They are identical in outline shape, same height and length but the DR650 is 1/4" thicker!

If you look at some of the Rigoli cars that produce around 740 hp(9 second 1/4 miler) there intercoolers are not that much bigger

Conrad

wrrjones

the FMIC on mine is quite thick this is on of the things that we liked about it and the pipe work is exellent bit fitting required so much cutting . this is one of the benifits of the APS the fitting aspect also the intercooler comes right up to the underside of the grill bit too high realy but like a said its just trail fit as it will have to come off for other things to be done ...... chris
