Seem decent enough but then again it's only 200hp or something These are for my 330ci convertible so not huge power, i was more interested in the wet braking ability say if you have to do an emergency stop. Some tyres have shockingly long wet braking distance compared to others, the Hancook Ventus was 8 metres more than the G/Y Eagle F1 https://www.tyrereviews.com/Article/2021-Auto-Zeitung-Summer-UHP-Tyre-Test.htm Edited August 23, 2021 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...

Got a good deal on Michelin PS4's last year and in the wet (accelerating and braking) they were a noticeably better than the GY's. But in the dry it's marginal, both are good when warm and they hook, F1's were more comfortable and quieter. I've had consistent results across various 18" tyre sizes 225/235/245/255/275 and 285 1 Quote Link to comment Share on other sites More sharing options...

Plenty more to go with the setup, but the autobox would go bang lol No idea how it's currently taking the power tbh! lol Edited August 24, 2021 by Burna (see edit history) Quote Link to comment Share on other sites More sharing options...
Noz Posted August 24, 2021 Share Posted August 24, 2021 How'd you get 640. I thought was 15%. I've got 525whp. Why I'm so curious. Different dyno tho Quote Link to comment Share on other sites More sharing options...

Different dyno tho I just use this https://www.mk5cortinaestate.co.uk/calculator4.php comes out pretty accurate. It was always said on here that it was 25% loss for autos, and 18% for manuals, but tbh it’s all about the rear wheel horsepower figure. 1 Quote Link to comment Share on other sites More sharing options...

Yeah I agree, but I like to use that converter so it puts it in my mind how it compares to Supra's I've known in the past, I'm VERY happy with the figure tbh! The main reason of the day was to check the setup since I went FMIC, and so glad I did and spent the money on an ETS, the IAT's actually drop to ambient when under full boost hahaha You won't see that on a cheap FMIC It has done a 550rwhp on a previous run, and Mike reckons we could have gone for 600rwhp, but I'll want to change to a built box before set it at those figures, I'm really pushing the poor autobox as it is Quote Link to comment Share on other sites More sharing options...

Top guy. Better safe than sorry mate. Good choice. I've seen ambient temps on a cheap cooler with 400hp. But it's never gonna happen with 600hp mate. I've a 4 inch ets. No idea when it'll start holding me back. Not for a while I guess! What's your end goal mate Quote Link to comment Share on other sites More sharing options...

The Vredestein Vorti R has the highest rolling resistance but not the best wet braking so other factors involved such as the design of the tread pattern and how it clears water The Potenza sport looks to have wet braking and handling sorted, you'd think it would win the straight aqua test but doesn't quite top the list, how does the Falken come second when its 7th in wet braking and wet handling ?

Because aquaplaning and wet breaking are strangely the opposite! Aquaplaning needs lots of grooves to disperse the water effectively and wet braking needs less so it has a bigger contact patch with the tarmac. Obviously it still needs some grooves as you wouldn't stop very well on slicks Quote Link to comment Share on other sites More sharing options...
