Non Sequential (Should I)

[TRex]

John easy fellar, off the box!

 I think everyone knows where you stand with this subject as I can surely do a search and see you have pounced on all the non seq thread and preached the same thing..
 \'No one is disputing\' what you said about power or lag or whatever your experiences were.. There is a bigger picture if you take the time to read.
 
 The guy is having mega problems with his car(for quite some time now), and he\'s fed up and more or less had enough..
 
 My advise to him is \'yes\', simplify the set up and run the Turbo\'s parallel.. this eliminates alot of crap and if there is problems further down the line, there would be far less things to have checked out!
 
 If you want to take this further, IMO it is a much better set up to have(parallel) for both reliablity and performance!

 But I\'m not gonna preach to the pope tonight.

I would like to say something here about non sequential conversions and the results.
I have carried out quite a large number of these conversions now.When I do so I allways tell the prospective customer that I will reverse the conversion FOC if they are not happy with it,to date out of the twenty to thirty conversions that I have done only two have had it reversed,I think that say\'s enough,but I AM going to say more.
I personally prefer to have the turbo\'s running non sequential on stockish twin turbo\'s that I have owned,and would not ever run my own car sequential again.

Hi Carl, I like your results... do mind expanding your reasons out of interest, f(fully understand if you do not want to get into a chat about it on here though mate..) :Thumbs-up

(edited to add) - Johns gone off line now anyway...lol

[Carl]

For one thing the car is much more predictable to chuck about in wet or dry conditions,as you don\'t have the torque fluctuating as you do with the boost dropping,and then coming back again, between change over on partial throttle with the sequential setup.
You do have to learn to drive the car differently on non sequential,using the gearbox more if you want boost,but if you are cruising you definately get more miles to the gallon.Also I think that the tuning has alot to do with satisfactory results from a customer point of view too.

Spot on Carl, I couldn\'t add to that really!

 
  Also the big point there is that the \'customer is always right\', this you have proven results with, we say no more! :Thumbs-up

Thanks carl I think you\'ve helped me make up my mind, the other reason is I\'m experimenting with designing a custom fuel setup and I think I need the space that the solenoids are in for some of it.

Good Luck, hope it solves your problems....

[John Yorke]

Same old same old, must be lots of happy non seq out there I will leave you to it , hope it solves your problems, mind you any decent tuner /  mechanic would solve your problems even if it mean replacing a few tubes and bits.......... Non seq is an easy option.

I reckon against something like a Skyline with 4wd you wouldnt stand a chance on a drag run, my Rex has enough trouble keeping up from standstill with sequential, let alone non seq. By the time the turbo comes on he\'d be 6-7 car lengths in front.

Keep us informed though mate.

[allstaruk]

Right after cafefull consideration, well a decent nights kip, I\'ve got two set of turbo\'s.

1st I\'m going to make my sequential system work (or pay somone too), and that will remind me of what its like to actually have a working sequential system.

2nd Convert my 2nd set to non-spequential swap them and see which one I like the most.

I will write up everything I\'ve done and put up a direct comparison of the two in my opinion, to see if we can shed some more light on this debate.

Well done that man:Thumbs-up I love it when someone actualy has a go and proves it one way or another.
The thing you have to remember is that most people who have gone non seq. are fed up with boost issues and it is a cheap way of solving the problem regardless of what it does to the way the car feels.
My personel experience was running 320ish atw on a fresh engine with no issues just trying to find some more power [didnt find any], I found it didnt suit my driving style and quickly changed to a single tubby and hiked the power up to 400atw before moving on to the RE engine.

[gmogle]

Yeah good on you mate.

Look forward to hearing the results.

The twin feel is fantastic when it works and the first time you get thrown back into your seat when the second turbo comes on is fantastic !!!

Its a completely different car to the Skyline as the twins arent sequential on that. It just feels a constant power.

[allstaruk]

To be honest I\'ve totally forgotten what the twins feel like when there working, I do remember it being good but, my only dislike is the turbo changin over mid corner and it really unsettling the car.

John,
I take strong exception to your remarks.
The implication of your words is that many do the non sequential conversion just cos thay have probs with the sequential setup not working properly,and it is the "EASY" option.
THAT IS NOT THE CASE!
Most if not all of the conversions we have done are on a standard perfectly working setup,it is just that the customer has wanted to have their car converted.
Also I do not know what all of this lag business is about,on a standing start,with the right tuning the non sequential setup works very well,just an adjustment in driving mentality with regards to revs off the mark is needed.
The car will be into boost pretty well straight away if it has been done and tuned right,obviously in your case it must have been done poorly,or you were not in sync with how to drive the setup.
