vvti

[jago]

drove a celica vvti (borrowed while elise in garage) on the weekend. absolutely gutless, which is down to weight i guess. But it just 'felt' like a different engine - the cam change was far less violent and pronounced, and it didn't feel like 190 bhp at all.

Different ecu, te lotus ECU is a vast improvement on the toyota version.

Mourn the passing of the supra...

Not strictly true.

Toyota do 2 versions - the VVTi is a 140bhp variable valve-timing engine. Even in the MR2 it feels lacking.

And then there's the VVTi-L, which includes variable valve-lift, a-la VTEC. It's this engine which is in the Elise, but only the Celica T-Sport (and a few older VVTi-L Celica's without the T-sport pack) in the Toyota range.

I suspect you drove the first one, which is no comparison. Having said that, the T-Sport doesn't feel rapid until near the redline, worse than my old 'teg for peakiness.

Ah i knew lotus had done some ECU work - but couldn't believe that was all the difference. I'm pretty sure i was driving the 140bhp then. makes sense.
