Hi Cubes, I know what pinging sounds like, but ive always wondered what to look for with the exhaust when knock occurs. I think it gives a puff of black smoke - if this is right, what would cause this? The air-fuel mix not completely burning under knock conditions? Cheers, Matt

And yeah, a pot is a far smarter idea Roy

This has to be the STUPIDEST thing I have ever heard done to a car.

"Hope this helps and for futer reference on the flow bench the rb26 inlet runs 145cfm as opposed to the exhaust running only 95cfm, the exhaust side of an rb26 sux big time!!!!!" This is usually the case with ANY engine though... Those readings are taken with the same pressure across them, but in reality, the pressure in the cylinder on the exhaust stroke is much, much higher than whats in the inlet manifold.. Thats not to say that you are wrong or anything, just saying that its not that unusual for a production engine. Cheers, Matt

I agree with disco, the YBD had some f**ked mods done to it to make the shitbox turbos work on them. It was a very sad turbo system indeed...

Whats the turbine A/R?

God I want that car Just need to sell my civic LOL Anyone want a 1999 VTiR Civic hatch? Cheers, Matt

Not too late to join? im after one for an R32 RB20

Lag just gives you more to look forward to.

Hi Bruno, nice result Where did you get your GT3037, and how much was it? which manifold is it sitting on? Thanks, Matt

"a t04e on by 4000rpm on an RB20? no chance if its a true t04e depends on the spec of it though etc. many variables" TO4 family turbos range from 200-650HP. The smallest will spool way before 4000, and the biggest will spool later. like you said it all depends.

Ive never seen so many of Dimitrios's mates in the one thread...

teh surge sux

Have you measured this with an AF/R meter or is this the behavior the car was showing when it was last tuned with normal PULP?

Heres the complete thread taken from pf.com. Theres a quote from a Dick Johnson article where he runs it through one of his V8 supercar engines as well. Very interesting read. http://pforums.company-hosting.com/forums/...29&page=1&pp=30 Hope this clears thing up a little. Matt

"So does every person need to retune their car when they put any fuels containing ethanol in their car. Doesn't sound very reasonable to me. Sounds idiotic to me..." Simple - its a different fuel with a slower burn characteristic. This is why most major car manufacturers reccomend you dont use it. Newer models of cars will be tuned with this in mind and will be compatible with the new fuel. I wouldnt say that I swear by the stuff - just that it has it uses. The difefference is quite considerable at idle/part throttle, given the fact that your engine is now most likely running far too lean - especially with cold start where a fat micture is mandatory to get and engine running. Taken from another forum:- For everybody interested in this thread, go down to your local newsagent and pick up the latest High Performance Imports, with the Red silvia/180 on the front. It has a test of this fuel (page 69) in an R32 GTR. Car was fitted with low mount turbo's exhaust, dumps, injectors and power FC. BEfore results tuned to as much timing as it could take were 289rwkw, they put E10 in the car, noticed it ran MUCH leaner, as it is less dense, has to add fuel everywhere in the map, they noticed on cruise it had risen from 14.2:1 up to 15:1. Under power it also went from 12.5:1 up to and over 13:1. This is not a bad thing overall, just don't put this stuff in your high performace car without tuning it to so=uit, as the next bit of info is the pudding. When now retuned to suit the fuel, tha car could take an extra 7 dgress of timing, and still register less overall "knocking" on the power FC warning meter, and made an extra 22rwkw when tuned to suit!! No other changes, just fuel and tune. Same car, same day. The noted that it had "similar tuning properties to other oxegenated 102-105 octane race unleaded fuels costing three times the price". END quote An extra 7 degrees is a BIG difference... This is why I think the fuel could have its uses.

E10 is great stuff... theres potential for a solid power gain over reeglar optimax. You need to retune your motor though. If you expect to be able to just chuck it in and "she'll be right mate" then you are an idiot and deserve a car that runs like complete shit.

You are correct, however its better to have the turbine housing matched to the application. you can then use a more conservative cam and get a better spread of power. Using a BIG cam to fix a SMALL turbine housing isnt a good combo. while it will help, you will find that the turbine housing only wants to work well ion the lower half of the rev range, while the longer duration exhaust cam will naturally want to work in the higher rev range. Its all about the combo

A warning to anyone that does read it - theres a few good posts, but lots more bullshit. some of those guys are on another planet with their thinking.

It may help a little if you advance the cam timing, but this is only a band aim solution that will have to be reversed if you address the cause of the problem (turbine housing)

Look at it this way, you're trying to use a 350hp turbine housing on a 600hp turbo. It just aint going to work to its full potential.

"Its not so much the flow but the cooling efficency that I am worried about. At 19 psi the air after turbo compression would be very hot, I though that maybe my cooler is not good enough to get the temps back down." Nup - this side of things is probably fine. Ive seen this before and im 100% positive that its the turbine housing causing backpressure which is making it overheat. Id be tapping the exhuast manifold and measuring that pressure in there. With a GT30, anything more than 1.5:1 ratio of backpressure to boost is too high. Cheers, Matt

What turbo and management is adpsi using on his engine? is it an R32 GTSt?

robocop - do you still have these DVD's I'd still love to get a copy.. can you email me/PM me please to work out payment?

I have seen jims work up close on a friends civic that made huge power... his tuning is top notch... Nothing wrong with it. He has been trusted with engines worth more than yours and hes delivered the goods many times. From what I can see in this thread, you got what you asked for - caveat emptor. Its your problem mate - not Jims.
