ye we have some updates.
running out of fuel as i have only the one pump installed and will be installing the dual Buschur soon and crank up the boost some more..we are droping in some kelofrd 280 cams and will retune soon and drop in some race gas and hopefully some 40psi Runs.We might be changing out hotside to bigger one as well but i am sure it will crack 700hp easy...
also bear in mind this is a 5000ft above sea level
453.8 Kw= 620 hp
728.4 Nm= 540 ft/lbs

- i have had terrible luck with dual intank fuel pumps, i strongly recommend keeping a single intanke pump, and using that to feed a bosch inline fuel pump. i have never been able to get a dual intank pump setup to work much better than a single intank and never better than walbro intank-> bosch inline
-very exciting to hear about the kelford cams, i had great results on a subaru we just built with them, make sure you play around with the cam gears +3->+5 intake cam gear -2->-4 exh cam gear and see where you end up
-your torque plot indicates you will definitely benefit from the new cams and may also benefit from the larger turbine housing

i bet there are very few vehicles that can keep up with you at this altitude...
exceptional results thus far esp with a 1.00 tcf -- would you mind rescaling your dynapack plots with HP and TQ rather than Nm and KW? There is plenty additional potential. my input is as follows:

ye I have been thinking about the fuel pump plenty hense why i have not installed my Buschur twin, and prob gonna go the BOSCH route Geoff.
We gonna drop in the cams first before we change out the exhaust housing, should be interesting, I can only change Exhaust cam as this car is a IX but when my tuner back he will work his magic with the MIVEC.
This car has spent no more than 40 minutes dialing in the timing and believe me there is more to come. Hoping for over 700hp @ 40psi...
I will try get the graphs for you in HP and ft/lbs and post back here
as updates become available i will post up.

well here is another update ....
E75 and 35psi
changing out housing to a bigger one..
also thing of note..
5500ft above sea l
also figures are in KW and NM
converted = 699 hp and 622 ft/lbs.

35 LBS and you made 699 HP and 622 LBS of torque....Good lord...can't wait to get my setup dialed in. Thanks for the updates. Just got to wait till spring time.

i use the same dyno to tune my car, so the squish isn't a problem.
here are my sheets
i was wanting to know the run time because it'll change the way it looks.
mine is on a "8sec" run, but it looks like his is 12sec or even longer with the steep ramp.

I will have to ask the tuner at hand.
it does break traction in second as it comes onto boost even in 3rd depending on surface.
Hold on to your hats@4000rpm..
also this was not printed out it was taken from screen shot.
I will try get the graph taken in HP and LBS and lay it on one sheet, and you will see the ramp up is not so agro..
Also why is your NM in hub nm... what is the correct figure

hub NM is just what my tuner uses, you just need to divide it by the ratio.
thats why setting up the ratio (final drive x gear selected) at the beginning of tuning it important. 4th is the closest to 1:1 ratio.
1764 / 4.68 = 377NMatw, =278.08 ft-lbs at the wheels for my sheet.
I noticed your sheets are 3.700 ratio, where they done in 3rd gear?
i can't wait to get my stroker built, even with 300kw it's going to be crazy in my light little car lol.
Nice work on the results though, your dyno sheets just look plain rediculous lol
Cheers, Mike

That's amazing torque. I'm not sure I've ever seen a 700 whp car make over 600 lb/ft of torque.

300kw is no prob dude.. what turbo are you planning on running..on a ams 30r @ 2 bar I managed 340kw on a dynapac.
if i would do this all again I would go and i suggest you go to a 2.2 stroker..
best of both worlds, the ability to rev and extra displacement.
but the idea is to crank out 670fl/lbs @ 40 psi.. I am sure it possible seeing that we only at 35psi
screw the hp torque is what is cool!!!
