11.2 @ 121mph - Series 7 with stock engine/turbos

cough hijack luv the avatar please tell us that\'s not you? cough

[Initial-D]

Just thinking the same thing, I\'d love a storm trooper costume for some reason!:D

na its not me, my mate at work got sent it, i thought it was well funny, I just had to use it!!! :rollin

[Glenn Butcher]

I hit him with another question on the duty - be good if some of you guys who have been there done that could fire some q\'s at him also

I\'m still amazed- it is an incredible time.

Ant - you around?  you had quite a bit of experience with this (very similar) set-up.

[BlitzBoy]

looking at the pics, I like the idea of him using two rx7 spare wheels for the front, must save some weight and rolling resitance, will the rubber be safe at those speeds

[MikeLMR]

Lol I\'m an expert now

no idea on the fuel system side, but what else has been done to the car ? don\'t forget a 11 sec 1/4 is much much easier if your car weighs feck all.

[Glenn Butcher]

Hi all,

Well - it is running stock pump/injectors etc.  :confused:

So - it is just plain impressive!  the rest of the thread has almost all the spec. information on the car.  He is going to post up the dyno pics. later today.

The turbo\'s aren\'t even the upgraded Series 8 ones!  just the Series 6/7 turbos.

[Schtoo]

From what I read around here, sounds like there is something he\'s not saying.

Maybe some kind of wacky fuel or some kind of extra octane booster (Toluene anyone?).  Was the IC iced up or maybe some kind of coolant on it. Maybe packed with dry ice, etc? Running big boost is fine, but even better if the air is cold, right? That could explain the big power, really cold air. Does he run giggle gas? Heck, you could make any POS run an 11 with enough octane points and enough oxygen.  

Doesn\'t matter who you are or who you sold your soul to, you still gotta obey some laws of physics and thermodynamics...

[Glenn Butcher]

Hi Schtoo,

I guess we\'ll wait and see what he posts on the Dyno sheets - I do believe what he has done is possible.

It isn\'t even a front mount IC!

[Glenn Butcher]

Sheets are there, I have calculated it to be roughly 420hp at the flywheel!

[Schtoo]

So, the sheets are there, and assuming they are correct there is one of two things occuring here.

1. He\'s doing something he is not saying (see previous post).

2. He is violating some fundamental physics and somehow getting away with it, in which case see point 1.

Even seeing timeslips, eyewitnesses, etc still does not explain how. I don\'t deny that he did run those times, but how is he getting the power with an inadequate (for that HP) fuel delivery system? Maybe he doens\'t know, or has been given wrong info on his car? If the thing was proffesionally prepped (souinds like it) then one of the first changes would have been pump and injectors.

I think he knows not what he has come to think of it. Like alot of folks, can drive the wheels off anything, but doesn\'t know how to put the wheels back on.

When will the feline expurge itself from the flexible containment device???

[BlitzBoy]

Schtoo I agree with on the "He is violating some fundamental physics" point

I seem to remember Bill Shurvington knows a lot about whats possiable, seen his good points on another thread.

yeah he is probably is a good driver but has no clue whats go on in his car before he bought it, he probably has an upgraded fuel system with out him knowing.

[bnaellis]

my t51r only has stock injectors at the mo. I It has done 14000 miles like this 1200 of them by me about 20 runs at pod and even disconnected boost controller and hits 1.5 bar and I have done alot of the miles doing burnouts at frequently hitting 9,000.
There is absolutely nop way it\'s supplying anywhere near enough fuel for this setup so I guess this guy\'s achievement is more than believable. Don\'t forget he got 1.6 60ft which is very good even by 4wd standards.

I have done a little homework on this, it just MAY be possible!    this is what I posted on Ausrotary...


SERIESvii!

Yes - I\'m still very interested in this!    I have been playing around a little in the Quarter Jnr program, and have found the following (screen dumps below):



Details:



I based the run on the mph figure, so it looks like you have around 410hp at the flywheel - which must mean your fuel system is on the limit! The weight I calculated as follows:

In kg\'s:
Car: 1310  (going from this spec. http://www.iluvmyrx7.com/3rdgen/manuals/95brochure/imagepages/image18.htm )
Driver: 70
Fuel: 26

Total: 1406kgs ... converted to 3100pounds.

I tried to match your timeslips as best possible.

Essentially it is the perfect launch/run!

Out of interest, if you were to put a 4.3/4.7 diff ratio in the car - it won\'t actually make that much difference to the time/mph.  It is weight of course that makes a big difference i.e. if you lose 100kgs you are in the 10\'s:  

[BlitzBoy]

damn I wish every stock engine/Stock turbo/stock fuel system RX7s could replicate that time and power, i wouldnt have to spend so much money in modding trying to get myself into the 12s :rolleyes:
