New filter setup ; straight to TB (pics)

[franx]

i was reading 172Ben's thread , he got some nice trumpets on there now , and saw that before the Throttle bodies came on he had a phase 1 airbox straigh on to the TB. Similar to the Cup racers setup, looked to be allright so i also gave it a trie !

Battery was already in the back, got the ecu out of the way by laying it on its side and finally made a ghetto heatshield. Worked out great ! I was very surprised by the car being a lot more responive and it seems a way better drive , i'm quite happy with it. Thanks Ben

Similar to the Cup racers setup,

How come the cup racers i've seen are all like this?

 

[franx]

Yep , seen that also on a couple of cars. This setup i did is also done by teams here in Holland (maybe they trie different setups ?) . Had a look at two of them last year and this setup was used .
By eliminating the elbow there is a real difference in throttle response, very direct and seems to have gained midrange too. Was just out for a little run and it feels really good, no flatspots anywhere just GO

i can say is its a big recommendation especially when on cams+inlets , exhaust ofcourse !

Looking good mate

Love the engine bay of the cup racer!

How much hassle is it to put the battery in the boot?

 

[franx]

route a big fat cable to the back (specs are on here ; search) . No Hassle at all (but i must say i HAD it done )

But it was a small job. Earth cable direct onto chassis in sparewheel compatiment

Thanks !


yeah that pic ; nice and clean , less weight up front ! Liking the strutbrace etc. too !

Done this today too, definitely feels more responsive yes!

 

[franx]

wisely done ! :approve:

Looks like a good setup.

 

[DannyR]

One of mine from today, could do with a feed to it, but may leave it Open, see how it goes!

 

[Beef-Mc]

That box looks fecking huge in that pic lol.

^ Is'nt yours stuck/rubbing on the right against the suspension ?

Because if so ; cut some more off the silicone tubing because it looks like it could lose some . Makes removing the filterhouse easier and allows for more "play" with enginemovement

btw; When i did'nt have a decent caf on + without the heatshield you could defo feel heatsoak going on when been in traffic.. afterwards was a lot better ! suggest you trie the cheap mod (piece of 1mm thick aluminium plate 100 by 60cm = 7pounds ! and a bit of airfeed + 15 pounds, or less ! )

 

[DannyR]

It is touching the turret yes! I can get away with another 15-20mm off of it I reckon. I've got some piping the same size as the hole in the box that went into it when it was down on a 45!

I'll get some more for it and seal it then a heat shield won't be needed

 

[franx]

Rob, was yours used in the magazine topic where different airfilters were tried/compared? Your pics without the bonnet seem familiar ?

 

[DannyR]

Rob? Do you mean me? Lol?! Its Danny

No wasn't used in a mag, was only taken yesterday!

That is the cup racer set up, but it's supposed to be with a green filter from memory

 

[Jonny1*2]

just noticed the engine mount is different in there. wierd.

 

[franx]

not "the set up " , it's one of ...

 

[franx]

just noticed the engine mount is different in there. wierd.

engine does'nt have mounts as we know it on a race/cup car. When it would be flexible the sequential box would have difficulties so all the flex is taken out. No flexible engine mounts on a cup

 

[Jonny1*2]

ah ok, didn't realise that. Makes sense though. Less body roll etc i guess.
