GT32 Posted May 19, 2009 Share Posted May 19, 2009 anyone who can help me would be great. just wanted to know how much power can u lose on a dyno reading due to having big rims on the car. i was told u can lose 15 to 20kw!...... is this right or shouldn't it make that much of a differance. thanks.. I recently took off my 17" Volk AV3's and temporarily fitted 18" Speedy Cheetahs and noticed a slight power decrease. I'm guessing that's due to the Japanese rims being lighter in weight. Wasn't very much but certainly noticable, so should be the same during a dyno run? I'm replacing those Cheetahs with Gram Lights next month anyway so hopefully I can reclaim that lost (1.5kw? ) power.

funkymonkey Posted May 20, 2009 Share Posted May 20, 2009 the wheels will add load to your hubs, which might make it marginally lower, but the kW difference should be negligible... however the added weight of the rims and the lower profile tyres will affect your handling much more noticeably. Also maybe people who run bigger wheels opt for cheaper/less grippier tyres, and therefore on a dyno there's more slip?

pharoahs33 Posted May 20, 2009 Author Share Posted May 20, 2009 So what ur saying is differance wise on the dyno it should be a little differant. It won't be a massive difference like 20 kw! LOL if u got 20"a on the car compared to the stockys 16"s can u lose 15 or even 20 kw atw if say i pull the 170 kw mark on the dyno.

bnr#@ Posted May 21, 2009 Share Posted May 21, 2009 You wont loose much power at all but you will find that the engine wont rev out as fast and in turn you will lose accelaration.

jakez88 Posted May 21, 2009 Share Posted May 21, 2009 so will i be ghey if i roll up in a stock r35 with stock 20s? LOL! an r35 gtr comes with 20" wheels stock so it wouldn't be ghey at all. however a 33 or 32 gtst with aftermarket chinese 20"s = ghey + chinese made - coolness = fail at life so jump off a bridge.
