running the twins non sequential how ?

[Donato]

It basically feels lik driving a small single, for the experience i have of sitting in a single turbo (didnt actually drive it though!)

[Mr J.T]

yeah thats what i heard. im single but have had a twin before would be cool to see the difference now

This conversation is starting to sound like a script from a carry on film... :Laugh

Is there any difference in terms of power delivery between the quick and the permenant non-sequential conversion? I had the quick conversion done and it does feel a bit gutless below 3K revs.

I done this permanantly to the twins I bought from Dragon, ported the WG to 1.25", angled and welded the gate and removed the manifold flapper.

Within a few journeys I was sold and the Single turbo was purchased!!!! I liked the twin seq, but the NS was Soooooooooooooooooooooooo much better for me and made me realise how much I wanted the single.

If its of any help, I still have all the parts inc the turbo pack (35k miles from Dragon), hard intake pipes, filters, manifold with gate removed and plugged inducer intake pipes, Y-pipe etc £350 if you\'re interested? just PM me.

FYI, you won\'t have PM facility as you are not a member mate.

cheers

You certainly can..

Would running twin hybrids help alleviate some of the lag when going non-seq ?

[Shyne]

Sorry Craig only just picked up on this post!!! I\'ll drop you a mail, cheers Donato, I only just noticed I don\'t have PMs on here, im slowly learning the MRC way! 8o)

Devils Ref: You can clip the primary comp to get it down or you can map some of the lag out aswell, but it really isn\'t as bad as you would think, 3.5k I think I was hitting 12psi. but for me the alleviation of the sequential system and everything that comes with it and the kick of boost when it comes online for the first time, I was sold on the Single and purchased within a few weeks of making the conversion!!!

What sort of rev range are we looking at between stock seq and non-seq then ?
Seqs come on boost about 2,500rpm for the first tub and 4,500rpm for the 2nd tub ?
What\'s the redline ?

Does the boost curve improve then for converting to non-seq ?

[carterjohn]

here is an excellent how to on the non permanent way,

I might have a few blockoff plates that I made up still at home if you want them

Non seq we are looking at boost from 4.5, gives a totaly wrong impression of a propper single turbo, if you look at a TO4e [about on par flow wise to the TT setup] you will see boost from 3K. Rev range will not alter unless you start porting.
Non seq. is a good quick fix for non boosting second turbo, imho it mucks up the responsiveness of the turbo\'ed rotary engine. If you cant be arsed to sort out the seq. setup go for it but it does dissapoint. HTH

[Devil\'s Refugee]

Thanks John. Was always under the impression a big single would be quite laggy, but from what you say if something like a T04e comes on boost at 3k then that\'s quite responsive for me. I might stick with the seq set up and change to single at a later date
