Hi all,

This caught my eye:

Pretty damn impressive.

Has Power FC, Larger Intercooler etc.

M/T Streets tyres, 1.6 0-60ft!

Thats brilliant, so us lot have just got to learn how to drive...

[davefrith]

Certainly bloody impressive !

[maximtaylor]

It\'s not fair - he can bounce it off the limiter and get away with it

He must be a fairly handy driver!

I would guess that he runs race fuel for his high boost antics? Things must get seriously hot in them rotors with the stock twins.

Seriously impressive stuff

I seem to recall someone in the high tens in the US too ... very impressive :cool

[BlitzBoy]

Over 350 at the wheels!!!! hmmm he must have modded his fuelling, there is no way he can be running on stock injectors or fuel pump.

If he hasnt the guy who mapped his car knows his stuff!!

Glen ask him about his fuel system will be interesting to know

[Initial-D]

That\'s impressive running on the stock twins, I can\'t imagine his turbos will live too long under that kinda pressure tho!

[Glenn Butcher]

Question about the fuel system has gone in.

I will also be amazed if it hangs together for ages - some serious hp, even with great tuning!

[Christopher]

He running 1.1 bar on stock twins? Are they good for that or not!

Also are the stock twins on the newer Rx-7 (2001) more reliable than say stock twins from a 1995 RX-7?

[davefrith]

not for long I wouldn\'t imagine

depends how heavy your foot is

[Glenn Butcher]

Well - if you look at the post, he says he is running stock pump/injectors!!!!!!!!!!!!!!!!!!!

Pretty amazing!  I wanna know when it lets go.

Good stuff.... I came accross an acceleration calculator a while a go here

http://www.rx7.com/accel_calculator.html

Not sure how accurate it is or how good my weight number is but to get a time of 11.2 you need to be putting out 420 rwhp. Here are the numbers I used

hp 420
weight 2875
shifts 3
tyre height 25

gives an ET of 11.27 and a speed of 126 mph.

Weight is everything... if you drop the weight by 400lbs you only need 360rwhp

Thats some awesome tuned stock motor.

Does it say any where that it is wheel hp to use?

600hp, 2695lb, 9.99

[paul C]

Yeah,

There is a ? icon next to the words Acceleration Calculator click on it and it gives you an example

no f***kin way can the standard fuel system supply enough juice for 350 plus rwhp let alone 420 rwhp to produce that time, dont care how well its tuned, I like to hear MikeLMR views on this.
The guy is hiding something!!!
