Title: Turbo Talk
Post by: ro284 on October 23, 2005, 02:47:10 PM
I found G@NDY\'S \'Big thanks to Carl,\' Thread very interesting, and wonder what the feeling is for going Non Sequential, after all you often have to be booting it a fair bit to get the benefit of the second turbo, @ high speed (not always possible!) and second turbo may catch you out on a bend when that kicks  in! So looks to me like you get more power at a more usable everyday range! So a few questions,! Better Acceleration with less lag or not?  How do Non seq twins compare to a single with spool up or effeciency? what size single would that set-up be close to or equal to? What would a Dyno graph look like compared to say Tricky\'s car @ 322? with the same mods but with twins? Any one got one? Fors and against?
Cheers Guys, Hoping to learn something here! well a lot in fact!

I had a T4E on my last 13B lump. It was very good ( I trashed the engine, but thats another stooory) Good Turbo, very little lag, quite flexable to. If you don\'t whant massive power but good alrounder single my vote goes for that one. :wiggle

Still hoping for more info on non seq! like when do they spool up compared to stock? is it when the first turbo on stock spools say 2500 rpm or when the second turbo spools up at say 4500, or somewhere different? these are very fast cars, but only if there is somewhere you can get over 125mph, my thoughts are to make more use of the power of turbo no 2, any more info please.
cheers Bob

Mine starts making boost around 2-2500 rpm slowly building up, then hitting full boost hard (mapped to 0.9 bar) around 4-4500rpm then pulls like a train all the way to the buzzer, i really do prefer it. And it only cost really £150 to do. Its worth giving it a try mate :yes
