btw 97km/h-210km/h which is 60-130 in 5,55sec from the last log on 4th only.

 

Other "amazing" thing is that Karol's car run safely rich, like you see ECU request 0.76 lambda in high rpms and car still put down these numbers

 

i have bosch motorsport injectors, only 3k euros for a set.
so I bought 3 pieces

 

What's the flow the injectors are rated at?

 

don't remember but as I remember my ecu guy reduced fuel pressure....or maybe not, don't remember.
as stock are up to 700ps those are at the begging.

 

Would it be possible to see some pictures about the engine and intercooling system you have?
I'm also interested in knowing the mods you have done.

 

Nice work! Thanks for the biz and hope those mods crush it at the track

 

Thanks Dan, you helped me a lot !

 

no pictures

there is one in my avatar showing one liquid cooler.

coolers:
two liquid coolers and heat exchanger produced by company provides radiators for redbull racing f1 team.

engine:
garrett turbos
external westgates
external blow off's
camshafts
injectors
no maf's
con rods
ecu
custom headers
76mm exhaust
spec map sensor

I think that is all.

 

There is no boost fall of or leaks! Boost on this tune is being controlled by the ECU, not the wastegates, fixed boost tuning is the easier thing to do, controlling boost with the ECU is the tuner's challenge.

His ECU tuner could go all the way up to 2 Bar if he wants at 4K RPMs, and then modulate boost to end at 1.5 bar at 7k RPMs and 1000HP for instance.

 

true.
my ecu guy asked me before he tune the ecu how I'm planning to use the car?
I said "I will do Le Mans 24 Hours race"
he said ok.

btw I'm still running with stock pistons, in his opinion this is absolutely max for them as pressure in combustion chamber is much higher....

 

Because of this I'm very interested in knowing more of your car's intercooling solution.

( I have a narrowbody car and there's yet no IC ducting to IC's, just outlets. Inlets are slightly tricky to build.
So far I haven't heard about a water-to-air IC that can take track use more than few laps...would like to get ones, would make a nice sleeper... )

 

Jean what mods do you have for 5.2 sec 100-200? I am doing similar times in a lighter 997tt with GT2 large vtgs and intake, cams, rods, ported cylinder heads, exhaust + flaps etc. Rated at 730-740hp /950nm.

 

It is a 5-6 yr old protomotive build with custom engine dyno tuning, 3.8 ltr, twin plug, no MAF, Garretts (old T04), IC, mechanical rockers, equal length headers, all internals upgraded. Car is 2WD, run made in 40C at less than 1.1 Bar and 1 shift. Injectors max out at 1.2 Bar because the car is for street/ track usage.

 

I believe it also depends on the size of the front radiator and effectiveness.
it's very difficult to build good working system.
but there is a lot of cars running with liquid systems, veyron for example.
