The comp housings, I believe, are the same size for 18g and 20g (just the comp wheel is bigger in the 20g). So your 18g's existing snail... might!... simply bolt onto the SC40 (if the bolt holes are in the same place, etc)....

 

held on with a sur clip mate and i got a 16g housing milled out to take a 18g wheel called them today and said can mill mine to take the 20g wheel £25

 

Wicked! All sorted then.

 

down side to having a top entry setup what sort of boost do they make ?

 

At least 1.3bar (as my old 93 WRX's 16g was mapped to 282 at 1.3 peak/1.1 held). And that was on the restrictive tiny OEM airbox/tiny TMIC, etc).

I reckon it'll make 1.4-1.5 bar peak easily enough (which should be good for the bhp you're after).

 

that on v-power cos i got my 18g holding at 1.5bar now have had it upto 2bar but that was a accident when i was mapping my self lol

 

Yeah sorry, it was on V-Power only.

If that SC40 works okay then you should see enough boost on meth+VP to get your numbers....

 

meth was the best thing i ever did cost me less and transformed the car

 

The best/easiest mod for 'free' extra power, for sure.

But I can't be arsed with the hassle of pre-ordering, fiddling at the petrol station etc., etc....

 

have you got a simtek cos i got mine with one map for 95 ron and the other for meth+tesco 99 ron then you dont have to worry about forgetting the meth and you can get the meth to your door if you fill right up each time it's alrigh really

 

True! And yes I do have Simtek. I didn't think about it like that. Yeah, the 2 maps give you that 'get out of jail' option! Cheers

I intend to move to a T.S. set-up with a TS SC42 (7cm) for a super-spooling 400+ car - prob upto 420 on V-P only.

And if I get the 2nd map on 20% meth, then that could feasibly make c.450bhp!

 

why you think i when to meth i get it 2 my door for about 50p a ltr got 2 100lfr drums in the garden

 

Yeah, it's win-win over a long term period of use, due to, effectively, the diluted costs at the pump!

More power/miles for less!

 

just wish i could run pure meth

 

Yeah, it'd be awesome! 50p a litre! Like being in the U.S.

But 100% meth ****s up seals and stuff don't it?

 

yeah 20% is ment to be the limit

 

Indeed.
