Hey peeps now iv went non-seq im wanting to reduce the turbo lag, is there ways of doing this without engine proting?
Im going to remove the y pipe and make a custom straight pipe to join to the intercooler, like jonos setup and straighten the elbow pipe, at the mo im startin to spool about 3300ish, would like to get to around 2600ish if possible, is there anything i cn do to help it along?
Toyed with making a custom uim with bigger bore to aid flow which in turn should help spool? lol any info would be much appreiciated
cheers
The easiest way would be to make the new pipework with SMALLER dia. pipes.
Fish
If running a constant trailing timing split close the gap in vacuum to about 3 degrees and taper it up as it comes into boost.

I have no idear what that means bud lol.. wayy too technical :P
Would running smaller pipework all round not restrict power tho?
pictures are welcome lol..
smaller pipework will increase air velocity which will give quicker spool but limit top end power. Get whoever does your mapping to tweek the maps to suit the non sequential set up.
Kevin
heres an old pic, iv got alot more room noo tho lol.. these are all the bends im going to remove, so are u saying fit smaller pipework to reduce the lag on all these pipes?
double post)))))))))))
if the spool time can be reduce on the mapping session to about 2600ish then thats kewl, didnt relise that cud be changed in the map..:)
sort the pipework and get it remapped is the way i\'d go. Never reduce pipe diameter as anything you gain low down you\'d lose at the top end.
Kevin
kewl cheers bud, well was the way i was planning on going to be honest, thought maybe there was something else i cud have done to help it a bit..
Speaking to jono he reckons he`s spooling a few hundred rpm`s sooner due to the new pipe he made :)
I`ll also port the lim as i havnt done this yet, ported the plenum n TB tho :)
Hi interloper393 I did this with mine. Seems to spool up quicker than 3300 I\'m sure but that mite be me hoping, would have like to remove some more of the bends form thepipe work but that was the best I could do with the pipes I had.
cheers
lol and another prob im guna relocate me filters too lol.. toyed with the idear of a vented wing with the filters inside.. we`ll see how that pans out :S
My apexi filters sit below the drivers light now and get plenty of cold air.
Easy to do.

Seriously, don\'t drive in the rain. I know someone who hydro locked their engine going through a puddle slightly deeper than they thought when they had their air filters mounted low like yourself. :eek
I was a little concerned as well on the motorway recently in bad rain and the spray was mad, natural WI
but its a sunday car and does not go out much anyway, any puddles and I stop and go around:)
Thank you for your advise dont want that hydrolock, not the way I want my engine to go pop.
ive got a cheaper solution

I was reading up on Anitlag, I think I read somewhere Fc-datalogit has an option to retard the timing when you come of the throttle, which is supposed to dump unburnt fuel into the exhaust manifold and the heat should ignite it which should keep your turbo spooling..??
I think its similar method to anti-lag used in rally cars.. dunno about the rotary, and it would probably destroy your turbo in no time ;)
The Antilag via Datalogit does not function for the FD Power FC, I have only seen the function enabled for the Power FC Pro for the Nissan Pulsar.
Yep antilag is not too friendly on your turbos.
The best way to get it spool earlier is to go back to sequential operation, mapping will help a little bit.
Or go nitrous that will spool the buggers up real quick lol
I have read about a safe installation of NOS which was throttle position operated (eg it came on after 80% throttle was open). I suppose this would work well?
I also read it was not very good to use it in the low gears? and below a certain rpm?
Nitrous looks like an interesting option, i like the idea of it being throttle operated rather than button operated, just for a little bit extra ;)
James
most proper NOS installs either only activate at WOT or are progessive eg percentage of throttle position and the amount of NOS injected can be rpm based as well.
But for a road car I wouldnt use it personally.
So for stock twins go for a remap to spool the turbos earlier of go back to sequential operation
interloper - your always up for a challenge, how about creating a system that could redirect exhaust flow from the turbo back through the exhaust manifold when your coming off the throttle??
:)

:rollin :rollin :rollin
you can get turbo shafts prety cheap that take anti lag with no probs, thanks to the cossie boys , even on flebay
I doubt if the ones on fleabay will fit the IHI mazda twin turbo pack lol
Go back to seq.
I\'m still running seq setup aswell mate so that will reduce the spool up.... & I told you... don\'t do it!!! total head ache & to be honest with you I don\'t know if there was a gain from doing it as I did a load at the same time & she hasn\'t been running properly for long enough to get it on the rollers to see the gains!!!!
Jono
if theres no gain then thats fine bud, its to tidy up the engine bay anyways so a win win situation, o and i love the non-seq setup lol
From my experience with the non-seq twin setup you\'re not going to get the spool much lower than you have.
Even on my old ported engine full boost was around 4k and spool started around 3.3 like you.
The only way you\'re ever going to get close to the seq spoll times are if you port and get for a small single. Otherwise you\'re going to have later boost AND slow spooling.
