What does 550 bhp give in terms of acceleration?

[B21]

Several folks have asked following the bigger turbos and tunes 'well how fast does it go?'

There are 3 issues with performance testing the car..

1) Where I live there is no access to a long, flat, open wide fast road to do any performance testing..this invalidates using a GPS data logger such as Dragy to come up with some standard figures as gradients impact the numbers.

2) The 0-60 is pretty brutal on the powertrain..somewhere north of 600 bhp there's a real danger of snapping drive axles and a bit further damage to the DCT box on full on drag starts.

3) Calculations show that with the current gearing, how the engine revs out and now holds peak power that the car given room should do between 190 and 200 mph..but that needs a lot of room.

I'm contemplating next year doing some high speed runs at Elvington.

However to paraphrase .since I'm not a Stig..we do have the Stig's Italian cousin.

I have a friend with a Yellow 35is in Rome..he's going down the same broad route..

Same CSRF down pipess, TTE500 turbos, Wagner EVO3 FMIC, tuner, similar turbo inlets,outlets, charge pipe and DCIS vs Mr.5 airbox mod..he doesn't have a LSD or big bore exhaust.

Engines tunes are very close.

He's now done some initial Dragy 100 kmph to 200 kmph acceleration figures (62 mph -125 mph)

And its pretty consistent around 7.78 seconds..

If you correlate the findings its pretty much linearly related to real BHP that any car produces..aerodynamic drag and subtleties don't really start to play that much in that time, distance and speed.

He looks comfy in the boot. I bet he could improve his time if he was in the driver seat. Just sayin’.

He's just ballast. So with all that power, the car can do a 'wheelie'.
The bootlid also doubles as an airbrake.

 

[buzyg]

I bet it's fun to enjoy the acceleration, with all that lovely torque. If it's even remotely like the ///MR aerowise though, it will try and take off above 170mph. So serious Aero may be required before you try high speed runs. :wink:

Now we’re cooking with gas, folks. By page 3 he’ll pick another 10 bhp.

I love the mods you have done and enjoy modding myself but personally don`t want to go the turbo / supercharger route . Looking at the reasons you have given for not being able to or not wanting to test due to possible damage does it make sense in your situation to go so far with mods ?

It depends what you want I suppose. Peters' car was probably about as quick from a standing start when it "only" had about 400 bhp as traction is the limiting factor, and unless you are a road tester do you really have so little mechanical sympathy to nail your own car from a standing start anyway? I don't!

But once on the move when traction isn't such an issue it must be epic. Anyway I'll find out in October on his Scottish Coast to Coast trip, assuming I can keep him in sight now and again. :lol:

 

[Busterboo]

The only 550bhp car I've driven was a Jaguar F-Type, prepared & performance-tested for demonstration. I drove it on a public road.

It was agile, but surprisingly stable, very quick from zero and I liked it a lot.

It was not difficult, however, to imagine it being a pain in the ar$e to drive regularly.

Very impressive..I'l have to se if my Italian cousin wants to rise to that challenge!..I suspect he's doing about 525 at the crank..but..your ponies seem very strong!

Mr Tidy makes the relevant observations..trying to get to 60 off the line over 300 bhp is more of a function of technique and outright lack of mechanical empathy..for example if 0-60 launch time is your focus you program the gearbox to increase the % slip of the wheels before traction control intervenes..

I've never indulged in 0-60 dashes..at worst a rolling start then floor it..

On any powertrain that started life at 300 bhp aqnd you take it to 550 bhp you have to expect limitations and bottlenecks..

There's the inevitable non linear relationship between power increase, cost and reliability..even a simple re-map on the 35i/35is often results in plugs and coilks giving up..

I do know that at 550bhp I'm a long way from the huys running 700-800 bhp and even those at the 900-1000 so I take some comfort from them.

Supercharging / turbo charging a normally NA car is definitely more demanding when compared to simply uprating components on a proven fully integrated and de-bugged existing turbo'd engine..

Thanks for the reply [ref]B21[/ref], and the input from [ref]Mr Tidy[/ref], I have re-read your post properly this time and see that you are referring to just doing performance logging rather than using your cars performance when driving . I also do not do any ( ok many ) 0 - 60 sprints due to the reasons discussed and mainly enjoy the mid range acceleration . I think 500bhp is more than enough and don`t really get the 1000bhp plus builds that are only used for the road but then that is probably due to the fact I have never driven one and may change my mind if I did .

Is it the challenge of chasing the performance figures and the build rather than having the performance that is the drive for you ?

The guys on the 500 BHP-1000bhp are essentially doing it for either structured or unstructured drag racing / sprints..the reality is their engines probably couldn’t sustain those power levers for more than a few seconds without either overheating or structural failure..

When I decided to do a 35is upgrade program I bought lots of bits before I started the program…

Had I known how easy it was to get to 400 BHP on stock turbos and what 400 BHP felt like on UK roads then I would never have gone onto subsequently fitting bigger turbos…but..I’d started so I saw the program out..and if I’m doing something I like to do the best job I can with the materials / skills I have to hand..

The only remotely good news is that any overtake that could have started to look tight now never is..just press the go peddle hard and close your eyes.. :tumbleweed: :driving: :rofl:

LoL I miss that in my Mazda Mx5. The MR could do that, just drop to 3rd gear, press the pedal and bam you where past.

oh to try and grow old gracefully and with no regrets. :wink:

Great answer Nice to have all that power for safe overtaking
