Fastest ever 1/4 mile?

Fastest ever 1/4 mile? Does anyone know? What sort of bhp? Jules

For a Fiat Coupe or ever?

found this dont know if its true but 11.9

paul.

and its a Porto too!

does anyone know if this car belongs to someone on here

Isn't that Mavrics motor ?

Thats Mavric's 500bhp coupe. I think Flea has done an 11.9 1/4 mile but with a slightly higher terminal speed than Mavric.

11.94 @ 121mph

Are you not going to make sure everyone knows you were a couple of thousandths quicker??

That record has stood for too long now.

Sorry did not know. has anyone made a 4x4 fiat coupe? if so how? Jules

Yes both 16vt and 20vt have been made.
CoupeIntegral has a 16vt in the projects section and there are 20vt4x4 in both the RWYB and the tuning section

4x4 16vt drag race ,my bad that's a 16

Do you have any recent run of the strip with the new setup Flea?

have a look on youtube for marcowind - worth seeing

Everyone knows that I'm sure, but I'm not sure if everyone knows that I was the first and only to do back to back 11 second runs




It has, the closest in the last couple of years has been Westcoupe and yourself with a 12.5 and 12.7 respectively.

It's not going to be easy to break that record without some significant measures. The problem I have is not wanting to change from a road car to a dedicated racer. For me it has to be done in full road trim save the tyres, so it's pretty much relying on raw grunt to get the job done!

I may have a good crack next year. If I strip it out, with some slicks and race fuel. I may get close. And of course lots of practice, I'm still a novice on the drag strip.

And my 12.38 in 2008, although I was a bit stripped out (seats and all the boot lining)

was that with sticky rubber Nigel?

I reckon both of you could bust the 12 second mark with a good run and Westcoupe too if he can stop breaking things!

Well if civics and bloody old tigras can do 10 second 1/4 mile times,then surely someone in a coupe turbo can get a mid 11 or maybe a low 11??

Well im guna try and get 13 or better tomorrow at santa pod, we will see. Ill let you all know, might post it on you tube or something. Jules

ordinary trackday tyres - better than road tyres, but not as good as Leighton's Hoosiers

The all time quickest 1/4 mile ever recorded was by stunt woman Kitty O'Neill in 1977 at an incredible 3.235 seconds @ 412.50 mph.

Although I reckon that this looks quite fast too: Somebody switch it off!!!!!

I do think 11.94 is a great time, but think the fastest guys should be a little quicker really, a fully stripped and well lightened coupe project car needs to be built! ;-)

this may be a silly question (or 2) as i know nothing of quarter mile runs etc..its just a matter of interest for me and of no import in the grand scheme of things ..an answer would be apreciated none the less.
is it possible to get under 13 with less than 380 bhp and 350ftlbs with a relatively small turbo (rsr)? and would comp ratios affect your likely times all else the same ..i mean would same car say with 8.1 be likely quicker across the quarter than the 9.1 set up...i understand there are many other factors involved but lets say with a competent 1/4 mile driver at the wheel..

The answer to 1 = yes.

The answer to 2 = no, not really. The compression ratio on a turbo engine drastically changes how the car is mapped, and how it behaves off/on boost. To say that a car is faster or slower over a 1/4 due to compression ratio is more than a bit contrived.

thanks suba..maybe if i explain myself better ...i am trying to grasp which would be the best way to achieve a good 1/4 time all i know is that the higher comp gives a little more off boost i am not sure about the difference on although i would like to know..i can understand how it would be better to have slightly lower comp in order to run higher boost /bigger turbo in order to use the turbo to make the bigger power...my interest is more in which way you would achieve a better result over a small distance like the 1/4..by using higher comp smaller quicker spooling turbo or a lower comp bigger turbo more boost...
do you see what i would like to understand better? it would be nice if rather than just getting an answer i could get an explanation...also what are the advantages and disadvantages of higher comp say 9.1 when on boost... can anyone fill my spongelike mind with a good laymans terms answer

What boost level generally does the RSR start to become infficient?

quite high i think but thats one for flea..i do think i once heard him say it could run 1.9 efficiently but that is probably a low gear or overboost situation? or i have completely missunderstood (as you can tell i am not an engineer)i may be talking out of my a**e here my memory and grasp of technical issues are not great

Who knows theres no compressor map as its not a garrett turbo its a hybrid.

technically its still a garret as its a gt28 r with a bigger comp wheel from the rs and this one has had the turbine done also although what they did i didnt ask..but as you point out its not a proper garret model but all its components are garret

Oh not disputing it CAN be made of garrett components but that doesn't make it a garrett turbo.

My main point being is there is no maps for it so efficencies etc are unknown. I'm also not desputing that its a good turbo especially on the coupe. Fast spool and circa 330bhp what more could you want

OK, I wont write an essay for you. There are plenty of books on forced induction tuning / mapping that you can buy if you want to read in detail.

High compression ratio = good performance off boost, smoother transition onto boost, and better response on boost. However you can't run as much boost without detonation

low compression ratio = rubbish off boost, but you can run big boost when the boost thumps in without detonation

For a 1/4 mile the car should never be off boost. All the big power drag skylines may well be road legal, but would drive like an utter dog on the road - low compression ratios with fat head gaskets, and no power below 5,000 rpm. However for a 1/4 up goes the rev limit, and the car gets launched at 6,000 rpm....you can get away with this as there's the AWD drivetrain.

With FWD I can't imagine a 6,000 rpm launch on road tyres in a car with 400bhp is going to be all that easy...

big thanks.. so its a detonation thing with higher comp and big boost? i take it that me personally on a little turbo like mine (rsr)and 9.1 would be able to run all i could get from it efficiently without that being an issue? with proper mapping of course.
i had realisised that with a coupe it would be an issue getting the power down at the off (i would be scared of breaking things personally) but then i am not planning to do them just interested in the way to go about it..it doesn't bear as much relevence to having a quick point to point road car as i had first thought it may, so thanks for that ..i really could talk about it all day(or rather put someone to sleep with questions) so much to know !

Yes! If you start another thread on this I'll post some more - but this one is getting dragged off topic a fair bit now.
