RICA, MBC's and boooooost !

[nobananas]

After finally getting my motor to run properly I was thinking of trying to address a boost problem that's been annoying me a little. Am I right in thinking that with RICA 304 I should be boosting 1.1 bar ?. At the moment I'm hitting about 0.8 constantly occasionally spiking to 1 bar (very occasionally). I know all the pipe works okay as I dug through it all last weekend trying to fix my other problems (the first thing I will do is check my boost gauge is reading correctly). I haven't pressure tested the intercooler which should be next on my list of things but I was wondering something. I used to run an MBC plumbed in between the BCS and the wastegate but I had it set to just a little over stock boost and it seemed to work well, pulled harder and would hit the boost I'd set without spiking and would hold perfectly but I removed it when I got Rica'd. Would it be safe to refit the MBC and set it to 1 bar to see if it will hold better, assumably the ecu will fuel correctly as the remap would be 'expecting' the higher boost level anyway or would I be better off leaving alone.

you could just put the mbs in the pipe from the actuator the run that pipe into the turbo compressour , and bypass the bcs, then it wont spike m8

you can run the MBC & the Rica, a few on here are running like that. All i will say tho is please be carefull, because the Rica will have raised/removed the factory ECU boost limit it will be possible to run too much boost with the MBC & bend a rod in the process

my old rica 304 used to boost 16 - 17 Psi for refference :)

mine peaks at 20 then drops to 13 and has been like for well over 4 months

[stevie69]

whats 20 and 13 in bar?mine drops of too.just wondering if mine is the same.

[t5 pete]

1bar = 14.5 psi

[Torch S70R]

sounds like a boost spike?
mine used to hold boost at 16psi but i did see it spike a couple of times, depends on the gauge as well :)

20psi would be 1.378949 bar
13psi would be 0.896317

lol 20 is near the temp gauge like lmao

[leet5r]

and theres no such thing as too much lol

thats where mine goes then drops about 2mm into the white pretty quick.

av had mine pointin to the temp gauge like , so a turned it down now it probs peaks there or there abouts then holds just under the end of the white

i've got NA gauges now so haven't got the boost to look at (Apexi records that), but got to try & get off the 140mph clock now lol, also got 8k rpm on the rev counter :biggrin:

That looks a we bit uncomfortable pedro !

Certainly don't want to kill it as the wife would then kill me LOL ! (her car you see, and her only means of getting to work). So are we saying that 1-1.1 bar of boost is probably safe and we are only wandering into dangerous territory if we go higher than that or start spiking ?

a had a run with me m8 who has a 18t and a proper 280bhp and there wasnt that much diff like m8 so am goin to leave it till after york then stick that t3t4 turbo on with external wastegate and some 550cc siemens

its alot better now i've tidied it up a bit mate
