Do you need to borrow my Pbox?

 

I think I have to re-learn how to drive it.

 

Thanks that would be great!!

Reading between the lines here... can't wait to see the results.

Justin, here on 6speed has all supporting mods, including rods and has 20Gs on the car. It is taking a little longer than expected to complete his car though.

Anyways, very interested to see your results.

 

HI,What supporting mods do you have??

 

* Proto K24/18G turbos old style
* DualAir intake pipes from 997TT Airbox directly down to Turbos (Custom)
* Upgraded pressure piping (Custom)
* Upgraded EVO Diverters
* Dual 044 Pumps in serial (Proto style)
* Larger fuel injectors 72 Lb (Don´t really remember Proto recommendation)
* Large X-Pipe Exhaust 3,5" (catless).
* 997TT mk2/997 GT2 RS Intercoolers

If I´m going E85 and 20G Billett I will of course upgrade to larger injektors!

But well, pretty much the same mods that you seem to have with some custom made touch! :-)

 

What did your car weigh when you ran the 133 trap speed and was that with the 650 kit installed? Imagine your car would have been around the 550 awhp area and that seems like it should have been running a little quicker trap speeds.

Hmmmm

 

Well maybe you are right?! It was with everything on without GT2RS IC back then.
It was about 1350KG at the time but with my huge wing on the rear end?! I only did one run and It probarbly wasn´t perfect?!
Do you think I should have a faster 100-200km/h time as well? 5.3sec is the best yet I think.

Not sure... remember the DA that day?

 

HI,I think those traps with K24/18s and pump gas sound about right??

 

Close enough I guess... K24/18G cars usually put down 550 on 93 on a Mustang Dyno (more pending mods and octane, right?) and I am under the impression that 550 aw on a Mustang Dyno and these cars would be trapping a little better than 133.

 

I take it you have replaced the clutch?

 

Well I can comment on this because we have done 18g and 20g installs. My own car was 20g, from 911tuning and Protomotive. On a tiptronic with an MKB upgraded box.

We have an 18g in the shop as well that is billet 18g. The 20g is not billet. The 20g kills the 18g billet - it is that simple, real life results.

There is a little more lag in the 20g (that was fitted with full y-pipe, 5 inch Ics, injectors, the works basically) but as soon as you are on it, the 20g pulls much harder than the 18g.

18g works well at 1.35 on pump, and on race gas 1.45 is fine. However, 20g can run 1.4 on pump, and 1.55 on race gas.

There is very little difference between and 18g and 20g at 1.35 bar, because the 20g does not wake up at 1.35 bar - don't get me wrong it is quick, but as soon as you take it to 1.45 bar + it is a different animal.

On a slow surface (worth 2-3 seconds in time compared to other places) the 20g car runs 200 in one mile in 28.25 seconds, with 300kph in 22.5 seconds.

The real advantage with the 18g is the fact that you don't have to do y-pipe etc. The 20g certainly costs more to do because of additional hardware.

The 20g above has a 6.14 in the list that was done with full weight car 1585kg + 2 person + 3/4 tank. I have run 5.85 before.

It really depends on what you want. I have moved on now from the 20g and in the middle of bigger engine build with bigger turbos etc.

I have taken people out in both the 18g and 20g. Customers immediately see the difference.

I would say there is 0.5-0.8 difference in 60-130 time between the two, maybe a little more. That is on pump with full weight car etc.

Agreed 100%. My 0-300kph time on the 20g's was 21.45 seconds at 1.44bar.
My 200 mph time was just below 28 seconds on my mile pull I believe. I need to pull the data again.

 

At 1.55 bar they are good for 19-20 seconds, but we test where all the other cars test so it is a good comparison. The problem is that it is on an incline to 300kph as seen in the image and the surface is rubbish.
