Just trying to find out what is a reasonable figure to get from the SC42 bb
and what would the max BHP be.

 

400bhp and upwards, I think there are cases of over 500.

 

I plan on getting one of these after Christmas after doing a bit of reading on SCs turbo thread. Depends on supporting mods & spec but on VPower close to 420 is the norm & with 20% Meth they can go over 500.

 

so what would the sc46 do on 20% meths?

 

Mid 500s with supporting mods

 

Cheers Richard I've not looked through the whole thread but have they got graphs with and without meths with spec of vehicle?

 

hi
ive got a sc 42 on mine and it made 450 on v- power and 482 on 20% meth

 

All the graphs are there. It'll take hours to read it all but the latest 42 & 46 graphs are towards the end of the thread.

 

sorry this is going to make me actually sound like a thick sh*t here but, will fitting a say SC42 turbo over the vf35 give me more power, if leaving the standard T/M and the rest of the sti ppp set up?

 

Impressive
i would be happy with 420 ish next year on mine.

 

Yes it will but will need mapping to put it right, its not just a case of "whack it on there and happy days"

 

i plan on getting rid of the prodrive map for the ecutek map, but want to do what the best i can to reach 370hp

 

You would also need to change the injectors depending on you`re target and if you have the factory prodrive exhaust system you will also have to change that as it get a bit restrictive at the 350bhp mark and above,

You can stick with the top mount and standard airbox, I`d say as an average the sc42 has a good 75 bhp over the vf35.

 

Probably but you'll need the correct mods to get the full benefit, FMIC will help but it's more about exhaust system & injectors as well as mapping.

 

cheers guys! exhaust im planning on blitz spec R, and for injectors they wasn't on my list of things as for cats i dont want to decat the downpipe as i cba with the mot issue, and i dont really want to go for the front mount unless really necessary

 

You won't need injectors to see you 370, you can leave it stock and with full decat or decent sports cat along with sc42 and the map should see you 380+ on a newage Sti, they can push over 400 but that's where it's said the injectors are pretty much at 100% duty although a fpr will help a little but better off changing them if you want the full potential of the turbo with meth for example

 

cheers mate i don't think i will be going meth, as my daily i can only imagine it to be alot of hassle

 

It's not that bad once your in a rhythm with it, just like going to the petrol station and fuelling up, be the biggest bang for your buck thas for sure getting mine sorted for the meth map shortly

 

how much is meth per gallon? is it expensive :P

 

Not sure on that one but its cheaper than v power

 

Twin fuel maps would let you add the Meth & switch maps when you want to run more power & then switch back when you want to go back to daily runner mode.

 

Twin fuel map not available with ecutek, though, as far as I know.

If you want twin fuel maps, you'll have to go "open source" (can of worms opened etc etc).

 

Ralphs graph


another vpower is lower and higher is 20% meth


Also Took the two sc42's off my racecar and both were fitted to newage sti's and made 410 and 420bhp at 1.5bar on vpower. Cant find picture of the graphs.

Found one of the graphs

 

Is that how it behaves on the road as well?

I'm currently playing around with different turbo ideas for the track car once the road car is sorted (grr), but that seems pretty late spooling for track IMO.

I wonder if I've made a mistake selling the TD05-20g I had..

 

Cars will perform better on the road as the conditions are obviousley more favourable..All cars are different and will give varying results depending on what mods are fitted to support the turbo,plus engine spec/health etc etc and of course what the cusatomer actually wants from the car..imho you havnt made a mistake selling the 20g Henrik as the SC42 will outperform it in every department on the correct car,assuming its a non billet 20g that is.

 

What does the sc42 hit 1bar of boost at on 05sti

 

At what point do i need (or not) to change the headers,
im hoping not to but advice would help
is there much difference?
next year FPR, 800cc or similar injectors FMIC if needed but again advice.

 

Depends what gear. Usually all hell breaks lose in the region of 3800-4000rpm depending on mods and thd car.

Standard headers probably a restriction from 400 bhp.

Newage sti ?
