To turbocharge or not?
Posted: Wed Apr 27, 2011 2:17 am
I need some feedback. I have 2 GTV6 3L's, the red one is stock standard & that I'm keeping that way, my white one though presently runs a Glenwood Motors big bore 3.5l.
I'm happy with the performance but after just finishing my 156GTA with big bore & turbo, well it's changed my perspective a little.
I have a brand new Alfa 75 3L box with the 3.5:1 ratio & LSD & initially I planned to fit that, remove the carbs & heads, Dawie was to fit Alfa 75 12V 3L heads & 6XJenvey ITB's, siimilar set up to my 147 with GoTech mngmt.
I've discussed the way forward with Dawie & now we are talking turbo. I stick with the big bore but replace the Ross high compression pistons for low compression versions, he suggested 9:1.
The big capacity ensures bigger power at lower boost, I'm looking at 0.5bar, running 95 pump gas & target is around 330-350hp at the wheels.
What's the opinion on here, should I go turbo or not?
Any advice? Is it worthwhile or better.
TX,
John
