Blair Posted December 17, 2009 Author Share Posted December 17, 2009 too technical for ya'll ;) ;) either that or very boring!! Quote Link to post Share on other sites
Driver Posted December 17, 2009 Share Posted December 17, 2009 its not too technical tbh, just trim and spec sizes, cam durations, and spool and turbo graphs or talking about them anywaynot technical once youve read into them abit previously Quote Link to post Share on other sites
TBDevelopments Posted December 23, 2009 Share Posted December 23, 2009 i agree there isn't really anything overly techincal in there at all, could go alot more indepth with turbocharger sellectionTimTB Developments Quote Link to post Share on other sites
ste91 Posted December 23, 2009 Share Posted December 23, 2009 It annoys me when people write "4-AGE" as opposed to "4A-GE". Quote Link to post Share on other sites

Glanza_cl Posted December 24, 2009 Share Posted December 24, 2009 was a good read lol not tech at all... my view was he should have used something along the gt28 series, but choosing possible a larger turbine housing. but yeah wont go into it haha. Quote Link to post Share on other sites
Keri-WMS Posted December 24, 2009 Share Posted December 24, 2009 I don't know the ins and outs of of turbo selection (only read a lot of the Graham Bell stuff), but the graph/map you see could really be called the "choose your best compromise" - increase each factor (bigger turbo for higher revving engine) and you will have some downsides (bigger turbo results in more lag).There's much more to it of course but that's what people going for the "ultimate" all the time forget, the boring sounding "best compromise" is normally faster 99% of the time while the "ultimate" is faster 1% of the time.Same goes for brakes, fit 380mm rotors and 8-pots to a Rover Mini and you WILL win pub top-trumps with your mates....but try and built a competitive car round it!!!!!

TBDevelopments Posted December 24, 2009 Share Posted December 24, 2009 well said, some people forget about the big picture sometimes when sellecting parts and building cars. I mean i've built some nice 600bhp mr2's in the past, very fast but you get them on the road and its just spinning up all the time and a well built 350bhp will leave it for dead.TimTB Developments Quote Link to post Share on other sites

TBDevelopments Posted December 24, 2009 Share Posted December 24, 2009 yeah we found the same with the 3sgte in the mr2. 500bhp is about the absolute limit on the road, 400bhp makes a nice going road car and i can built that prietty reliably. Drag racing is another story though, were at 955bhp with that, can't drive that on the road at all, spins in 5th frm just flooring the accelorator at 100mph lol, but drag its capable of 9'ssorry for going off topic but i take it you had some cossie background, thats where i cut my teeth building engines built my first one at 14 ;)TimTB Developments Quote Link to post Share on other sites

While we're off topic my mate has a 240bhp n/a YB in his Mk1 on Jenveys, but he's selling the engine to make was for a 2.4 YB headed 300bhp beastie, Holbay/Warrior (or "Diamond-something") alloy block.
