very true, and i cant but agree that the charge fuel temperature will be way to hot not to cause fuel premature combustion. and true that its all about flow, that is, quoting howard coleman, that say a TO4R with 960cfm, that is about 75lbs per min.

therefore, 75lbs/min x 10 ( max power poss produced on pisssston)= 750BHP/1.3 power converstion for the rotary pulse train = circa 575bhp.

this is at max boost and i may be wrong here but in the 28psi range accourding to a pressure ratio chart i saw.

so, with this arguement and my experience, forget non sequential if you want to run high power with just 15 -17 psi of boost known safe boost area for the 93 octane pump fuel.

I may have been misunderstood...I never said i ran 1.7 bar...intenionally. the result of un intentional, erranious, call it what you want, over boost in fact caused me a broken seal and a collapsed rotor, as is the common tendency.

What i meant was, and i apologise if i was misunderstood, that the stock units ARE capable of boosting...but not safely, as you rightly said due to the heat generation, flows etc. I agree with you there, but i have to disagree that you would rather stay non seq. plus having two turboes will eventully effect you surge line since both turboes are of a different flow capacity. 15psi is in my opinion the hardest you can run the hitachi units with out melting them out, or damaging your engine.

You are not limited in regards to boost. you can still boost them up if you want to 20 psi, reducing their longativity, using the supporting mods like water injection etc, but no way you can get the single's power for the same boost...as you rightly said its all on flow. but, rest assured, you can boost those turbos and they will develop some power(<400) with just boost. you need extreemly conservative figures. i just think they are not worth the hassle....

Also if you read further on the post i also said that I am changing over to the to4r, now why would i do that if the stock non seq twins are so great?:P

I guess i was not clear, so i hope this clarification is ok.

ps...happy Xmass!

I think we are both on the same page George, just explaining it a different way. The main limiting factor I was talking about was the fear of the longativity of the turbos. My experience was the bang for the buck factor more than anything. I personally loved the car in the CB, DP, and intake state. Just because you could buy a CB and DP off of ebay for 400 dollars, and a 40 dollar intake cone dual filter setup, and violla it ran pretty quick. 440 dollars to run low 13's on factory fuel, ECU, etc. All the next phases after that seemed to be thousands of dollars of mods for a moderate gain that didn't give me a feeling of wow that was worth it. It's alittle late, but merry xmas and have a great new year.

hehe...yep, sayin the same thing but different perspsective.... but true, i agree with you....the more you spend sometimes i wish mine was still bone stock....

all the best to you too.... and hope you have a great 2006
