[peterwolds]

picking car up from wgt wednesday wastegate modified, power is now 305 at wheels, 360 flywheel, fuel pump fitted is a Walboro 255lit/min, additional injectors are 2 x  550 cc plus trust greddy smic fitted pip says goes well boost straight line

[peterwolds]

whats the next stage to up the power,staying with twins

good figures there with twins....WI may help also to up the boost a bit with Ignition Amp and some good plugs...:Thumbsup!

Cheers trouble is we are never satisfied always want more like oliver twist
Got NGK 9\'s all round,looked at WMI before deciding on greddy SMIC instead,Pip mapped and is known for being safe - not a bad thing

[Laeeq]

Greddy SMIC is the best...what boost are you running at present...

Pete,

I made 322 atw on stock twins, with WI and the rest @ 1 bar boost.  Blew the tubs shortly after.  Now I have gone single and it is infinitely better

The stock tubs don\'t like being runover stock boost levels for too long, as I found out

Not only this but because they are so small (in comparison to a nice fat single) they heat the air up a lot more which can\'t be good for the engine

If you want MORE power, I would with the benefit of experince recommend you think about going single.  IMHO the stock twins are not work much more than 320 atw.

And when you go single, trust me you don\'t feel like you need more..  I have been running on the low setting of 0.8 bar and it is more than enough infinitely better than the stock twins

You can get a HKS twin spark for less than that (pm me). Im making 320atw running at 0.95bar. I\'ve topped out the turbos, but they seem to be ok for the minute. Insurance is usually a bigger headache with a big single.

only want short bursts for drag strip, sure i read someone on here runs stock twins and pulls something like 380 rwhp ,must be in a table here - i would be happy (for now LOL ) with 340rwhp.Have a desire to stay twins, dont know why just got it in my mind - engines nice & strong year ago it got 8.4 fronts and 8.3 rears on compression test at reworx
Thanks for input mate,appreciated - maybe in the future will consider singles but dont want to throw a shed load of £££££££££ just now at car

380rwhp was John\'s "Warthog" car and he had extensive work done to get it at to stage! e.g using cosmo engine parts etc

[AtomicRex]

And he still gets overtaken by a golf diesel!
