I've tried searching and cannot find a answer to this, if i increse the boost how much horsepower will i gain?
it depends what supporting modification you have made, and how much you turn up the boost. and there is no way of knowing as ever car is different. its a bit of a strange question really.
will turning the boost up give you more power, yes.
can people tell you how much, no

Both wrong wrong wrong - Set your EBC to 40psi, and expect to see gains of 200-300bhp.
Fit a fuel controller and larger injectors and you should be able to run 300psi, and see 600bhp.
Chiro, your question:
1) could be answered by searching. A lot.
2) is poorly thought out - how much are you tuning up the boost by?
3) doesn't make sense as all cars, fuels, mods and temperatures are different
Yep - no sensible answer to your question.
Although as stupid as Alans answer is, it is probably not far off the mark!
A well set up electronic boost controller can change your 0-60 from 6.5seconds to 5.5 seconds. That is far more interesting than a small change in peak power, IMO.
Uve only had it 5 mins Chris & u already want to up the power.

My answer wasnt stupid, your just jealous you never got there 1st.
your all wrong youll get seventy trillion horse power for 80psi of boost!!!

I think the Max power chavs may fall for that one.
I was just after a vague figure of how much extra power I would get. I just want to know if I increase the boost by a couple of psi will it make a noticable difference to performance? Ie is it worth doing? Sensible answers only please
There is a noticeable difference from going from stock boost to say up to 1bar or 14.5psi. Its a massively noticable difference and you will shave off at least 1s to 1.5s off the quarter mile time.
Up the boost to a more manageable 0.8bar or about 11-12psi and you will be looking at a noticeable boost improvement and up to a second or so.
You wont get figures from anyone but expect to go from 260bhp to about 285bhp by upping from stock to about 12psi. That said, you might not get any performance improvement. It MASSIVELY depends on how well the car is tuned to receive the extra power.

ive been advised to get a gouge fitted to see how the boost works then fit the controler in a few weeks later but need to upgrade your pugds and leads too

Does it matter what type of EBC you go for to increase the boost?
i use a mbc works nearly as well
ive been advised to get a gouge fitted to see how the boost works then fit the controler in a few weeks later but need to upgrade your pugds and leads too
guage yes, ebc or mbc yes, plugs and leads???? who are they kidding???
who gave you this very useful knowledge so i can avoid them??
An MBC works well enough and provided you undertstand it, there is no reason why an MBC cant be as effective as an EBC.
But an EBC will manage your peak boost better and hold it steady through the rev range. Some EBCs are better than others, but essentially they do the same thing. The fancy ones have much more parameters and readings and results and graphs etc. A simple one will still keep your peak boost optimised but you wont get any additional info or the adjustability.
Just to add, that it is frustrating to not get answers to your questions. Everyone starts somewhere and your knowledge base has to begin somewhere, but these kind of questions have been asked SO many times. It is well worth a read up on some old threads on everything. I'd recommend picking a topic, searching and just browsing through all the threads that come up back to day one of CVR4. There was a LOT of information put on the forums in the early days, and you get to see the problems they dealt with and how they overcame it. It will help you in learning how and why these current 'recommendations' have come about over the last 7 years of CVR4.
Steelie, it has been VERY WELL DOCUMENTED on these forums that the '6' series plugs run colder than the '7' series. If you are planning on modifying your car to handle an extra 50bhp, surely it is a sensible upgrade to change your plugs BEFORE your engine blows up because your 'stock' plugs cant handle the extra demand put on them?
Erm, seeing as the long standing members of the forum, the people who have owned and tuned their own vr4's have suggested its wise to upgrade the plugs then I would think its sensible advice. Going by what I have read on other forums and websites over the years, it seems to make sense.
As for leads, I suppose thats just a personal choice but imo if you are already changing the plugs then why not get some uprated leads at the same time. Thats what I intend to do anyway
Everyone on the forums here
turbo steve gave me this advise and im not assed he gotto be one of the most nolagable members on here i have lisened to him and take his advise on bord
