Non Sequential (Should I)

John Yorke · November 18, 2006, 05:24:58 PM

Carl: Best of luck mate, I respect you for what you are, I dont have to agree with everything you say and it is a shame you come on a public forum with this attitude, you may be a respected engine builder but it does not mean you have the difinitive answers, your comments would be more acceptable if they were backed up with fact, we can all spout about how many conversions we have done but as I stated before, having carried out before and after conversion tests I found no improvment in performance.
I am realy glad you know so much more than Mazda on the setup of these engines, I am sure Mazda are pleased that having spent years in developing the sequential setup you have found the answer in stripping out their controll system and \'improving\' it.
Maybe the answer would be for you to prove in on the dyno - put a car on the rollers with a propperly tuned set of seq. twins then back to back it with your setup............. just like I did.
All the best:WaveBye

Imagine you have a bag of blackjacks & fruit salads. And you like the fruit salads, but you try one of the blackjacks and don\'t like it.

Then, you see there are a lot of other people who are still eating the blackjacks. Should they not eat them and only have fruit salads, just because you don\'t like them?

Thought not.
End of.

Perfectly sums it up!

Personally I like both ;-)

TRex · November 18, 2006, 06:21:18 PM

I like neither Blackjacks or fruit salads....

A good ole banana though.... :yes :mmmm

Since real life facts don\'t seem to deter you,
I best bow to your superior knowledge, as indeed everyone else obviously must then John.:god

Oh dear, another thread...another arguement. I think we should just agree that John doesnt like the conversion and Carl does.....end of.

I think it would be really useful if someone who has this setup (or maybe Carl himself) to post up some dyno figures.

I myself would be interested to see what sort of power the non sequential conversion can make and maybe the graph to see the power curve.

Also if you do the full non sequential conversion does this set you up nicely in the future to move to a single turbo should you decide to go that way (obviously with fuel mods being needed and a remap). But by changing does this mean that no further rats nest work is needed ?

Smifta · November 18, 2006, 07:16:40 PM

I do have power graphs etc for the poor-man\'s non-seq conversion. I\'ll be happy to post them on Monday. My car is a fair way from stock though (although you\'re not likely to go non-seq without accompying breathing mods, at least).

Jit · November 18, 2006, 07:18:12 PM

there shouldnt be any peak power gains from doing the non-seq...at the end of the day, at peak power on both setups, both turbos will be blowing the same amount of air at that particular rpm. the whole argument is about driveability and simplicity. Im staying seq because its standard and runs the stock ecu if you arent running modified. I also like the idea of 2 hits of boost. As long as you have decent enough mods (ie catback and downpipe), i cant really see lag being an issue.
Its a shame so many people are going non-seq or single turbo tho..like i said earlier, there prolly wont be any seqs left soon! Almost everyone ive spoken to (apart from Tim @ RX Motors) seems to prefer the non-seq.

TRex · November 18, 2006, 07:42:11 PM

Jesus christ, you people have got to be doing this on purpose! :2Rolleyes

Look, no one said anything about BHP, Single Turbo\'s, Dyno\'s or Skylines but you people for heck sake!

Jeezee the bloke(how many times have I said this) is having problems with his car and is looking to get it working and simplisity is the option to help him with his problem..
He is not looking for performance gains or mod advise.. he just wants his car working with no problems!

What the heck is so hard to understand there! :2Confused

Carl kindly stepped in to offer his advise (from experience which none of you have compared) and the rubbish talk still rolls on!

Carl:

Not at all mate, you have an opinion as well as everyone else. I am just pleased that All starstruck is having a go and is prepared to see which he prefures, you on the other hand seem to have the high and mighty attitude that quite honestly does not suit you, mind I should realise that when you are involved in a thread it inevetably becomes catty.
I will leave you to it, best of luck with your experiments.
Oh I like all three - blackjacks, fruit salad and bananas:)

QuoteSame old same old, must be lots of happy non seq out there I will leave you to it

is that a promise this time? Pot Kettle.

Many thanks for all the info Carl, nice to see some Tech info, backed up by huge experience,

dj_dee99 · November 18, 2006, 08:28:45 PM

Amen to that.

I, too, would rather take note of someone who has a great deal of experience in these matters, as opposed to the ramblings of a NON MEMBER! lol!!!! :Talking1

No need to gang up on john. He is just saying his opinion.

TRex · November 18, 2006, 09:26:39 PM

No one is ganging up, I just found that chaps comment quite amusing thats all..
