Hi there
I took out my friends today, the yellow Whipple one with circa 700BHP. Roads mainly dry and to my surprise it puts the power down quite well.
1st gear: It goes and it smokes them.
2nd gear: Roll into smooth and it puts the power down very well.
3rd gear and above: No issues!
I was expecting it to be tail happy and breaking traction but it does not, yes if it was colder and greasy for sure it would but today is 6c and most roads have dried out and it put the power down well, very well infact. In comparison my mates M5 has 560BHP and it struggles like crazy in 2nd and 3rd to put power down, but he is running on Pzero and we know that going to MPSS like Mac has on the Mustang makes a vast improvement in traction.
City driving I'd say it drives better than stock, the throttle does very little in the first 1000-2000rpm making it very smooth and easy to drive, you could let your gran take it to the shops without issue.
Partial throttle again nice and smooth, maybe a touch less initial get up and go compared to a tuned NA car due to the fact a blown upon car has to run a lot less timing for obvious safety reasons but once the revs are over 3000rpm partial throttle pull is superb and is just as easy to manage as stock if not easier.
WOT, wide open throttle is insane, if you plan to go full acceleration in 2nd or 3rd you need to be ready to change gear, because 2nd gear and 3rd gear are over in seconds and this is with no wheelspin, they are just over in a blink. Mac was saying rev it more, as I was changing up at 6500-7000rpm, I was scared to try and change higher with how fast the revs climbed and did not want to be bouncing of limiter which is somewhere around 8000rpm I believe, literally blink and you will miss it.
I even did a 5th gear pull from 3000rpm and the car just instantly woke up and teared of down the road, this thing would pull to 160mph so easily, its just over in no time at all. It is frightening quick and the fact that 700BHP+ still works on a dry winters day is impressive.
In short it is damn impressive, it has not become a nightmare to drive, it drives just like a stock car, infact it drives better. Just when you go past 50% throttle you can feel there is something much more and mashing the loud pedal to the floor is like engaging the hyper driver on the Millennium Falcon, it just goes, I can see why they make 200mph so easy when blown upon.
My only complaint is its all a bit too frantic when you get on it, get in the loud pedal for a few seconds and you are well beyond a 100mph, just end up going too quick and this is in a manual, in an automatic where the involvement is reduced this would be a go to jail card way too easily.
But I love it, I think I will end up going FI, my only recommendation would be to Mac and if/when I do it I would probably fit some longer gears like a 3.31 or 3.15 to make 2nd, 3rd and 4th well last a bit longer, plus they would aid any traction issues also.
I am watching the single Turbo options as for $4995 and 750BHP they are good value, but un-proven and a turbo could drive like poo, though its modern stuff, twin scroll and all that so no doubt pretty good.
My favourite option right now is an ATI Pro Charger Kit (Centri), its a true 100% reversible bolt-on that I can do at home. $6000 and power is 650-1000BHP, depending on pulley, fuel system ran etc. I'd start with a low 8psi and see how I get on. This system is also lightweight and has no negative impact on intake temperatures or heatsoak, making it also very track day friendly.
Or Whipple, the noise (whine) and more low/mid-range ooomph is nice but not crazy too much like a Roots style blower like the Roush but still more than a Centri style. Heat is an issue with this style of blower both heat soak and intake temperatures though it seems to have little to no impact on daily driving and of course this system has the biggest weight penalty and cost the most. But it drives perfect, sounds great and works. Would be nice to get to drive a Pro Charged car, but not easy, I am off to USA in a couple of weeks so going to see if anyone on M6G with a Procharger would be willing to meet up and take me for a spin.
