With e85 everything just starts sooner, more chaos sooner on. Also seems smoother to me no fuel smell but really it’s more for track methinks.Yes mines at 2 bar,was thinking of e85,but for once im really happy at where its at. Next step i want is the big alcon brake set up.
Its really hard to imagine 1500 - 2000hp
At 1.6 bar how does it compare to your old 4.5?I went from a 4.5 740 hp to a 1000/780 and the difference is night and day. I for one dont seem to be able to get used to that power,infact its mainly run at 1.6 bar which is lovely on the road. I love the car though gives me a real buzz and hopefully try for some events this year.
I am at 4.25 with an Alpha upgraded intercooler right now and for the life of me, I can't decide on whether to go down the 1000hp route or use that money to jump ships and go down the 720s route. Must change my mind every other day.Well I cant compare because at 4.33 (i didnt have the hybrid turbo's done). Just everything before you start changing turbo's etc.
You cant really go on one car as an example,maybe he had a bad launch,all differenty varients to consider,but as an average a 4.25 car will be around 10.8. A 4.25 car is way quicker than stock mateI'm torn a little between Stage 2 I'm currently on and going to Stage 4.25.
What is actually the quarter mile you should be getting on 4.25? I'm sure I have heard of sub 11 second times but I watched a YouTube yesterday of Calvin's Car diary where he was at Santa Pod with his RS6 and another GTR 4.25 only managed 11.5 which to me seems slower than stock almost?
Agree but in the video Calvin said his previous GTR 4.25 only ran 11.5 as well so that's pretty poor I thought. I can only imagine these 2 GTRs didn't launch that well. I know there is no improvement to 0-60 times with 4.25 than stock due to already aggressive gearing but you expect a lot better performance from 4th gear onwards.You cant really go on one car as an example,maybe he had a bad launch,all differenty varients to consider,but as an average a 4.25 car will be around 10.8.

I would like a bit more power so maybe Stage 4 would be better?Looking back I would stick at stage 2 because for me the extra noise, drone and performance were negatives compared to standard --> stage 2. The next huge jump is very very expensive and that's beyond the stage 5 level :-( when you are now at the limit of grip of your tyres so you know 'thats it' to me the big big numbers (way beyond 1000 bhp) are only for the strip with fat tyres, stripped car, etc as I cant see on track or road what much difference it would make.
sounds reasonable the added torque will help also. I’m going to go with Racecal Romain (Syvecs, Toucan screen) to control traction, launch, etc.I would like a bit more power so maybe Stage 4 would be better?
My current Stage 2 dyno'd at Litchfield made 620HP and 555 ft/lb of torque, would be happy with around 670HP and 600 ft/lb with next tune.
Positives of Stage 4 would be to keep primary CAT so less drone, no black soot/fuel smell and car is MOT legal.
Was the drone that bad for 4.25? I don't really do much motorway miles but obviously don't want it if I can help. I've got a draggy but haven't had a chance to use it yet so may record some times sometime so I can compare.
