1,000 HP evo
this is a REALLY common misconception about cars; higher hp does not equal higher top speed. it only helps you reach your top speed faster. if you want a higher top speed, you'll need to either swap the transmission out or change the gear ratio (changing gears basically). i guess it is possible to get a slightly higher top speed if your redline increases from building the engine stronger, but it wouldn't be as much as gearing out more.

The car runs good, actually too good. Low boost (22psi) right now pulls like 34psi before... Sam einjector duty cycle ( 50% at 34 psi and 55% at 22psi now). It is scary...

Even if your 4cyl was 2.6L, the GTR motor would be capable of higher power levels due to the flow of air being distributed through more cylinders. If the ports on both motors each can flow the same amount, the GTR motor can flow more air than the Evo motor and therefore make more power.... in other words, the ports become the restriction, max CFM of ports x number of ports = max airflow of engine. The GTR motor would make more HP since it can flow more air, this greater level of airflow would require more revs, which is why that 1200HP GTR revs so high. Since HP is a function of RPM, it would make more.... I hate it when things like this pop in my head and make perfect sense to me but I have a difficult time putting it into words. HTH and makes sense...
Nevertheless, badass car and I can't wait to see some dyno sheets.

I was at the shop monday and George started the car for me.....It blew me away... I never heard a sound like that from a street car
If the performance is good as the sound then the Porsche killer is born!!!

This thing is really coming together. Well done mate.
You should see a gain if you run twin (or even triple) 800-1000cc injectors in the JUN manifold. The second set of injectors that are furtherer away from the head give the fuel more time to mix with the air. The better mixing helps to make more power and gives better cooling!!! Ask Norris Design about the specifics as that is what he runs (2 x 700cc per cylinder and makes over 800bhp).
Are you running water injection? Should help with the temps and let you run loads more advance and psi. Methanol and water would help even more. I bet you could get 1000bhp if you ran methanol instead of race gas!
You have said that you will only use the N2O to aid with spool up, are you sticking to this or will you let it run at the upper end to?
Come on George, it’s about time you guys over there started to make some of the UK tuners worried!
Thanks Chris.
Ps. How’s the stock GSR rear diff holding out? No trouble with it yet? You going to upgrade it to the RS or you going for some custom thing?
EDIT: Norris Design has seen 200mph from his 800bhp EVO VII!
