ProMAX Level 4

I didn't thing 359bhp felt that fast, Patrick. I do think there's something wrong with me though because I have never been impressed by the sheer power of any car.
Thats because you can still breath, enough acceleration is when the car is so fast you struggle to breath hence the body provides the practical limit.
 
I guess there's also a perception thing as time progresses. In other words we are used to greater speed, power, handling nowdays more than the past. It's a little like nudity and swearing on TV. Look at how much there is now everywhere and we have become acclimatised to it. We get in cars that 10 or 15 years ago would have got us bugeyed and now we don't bat an eyelid. Time huh? I wonder if I can sue God on the basis that time is making me spend way too much on my car???

Fen - I'm sure there are cars out there that will hit he spot for you, although I doubt if 359 bhp will feel a whole lot faster than 300 in the same car.
It depends so much on the car - 145 mph through Fuchsrohe in the ring taxi felt reasonably sedate.

You're absolurtely right, though it's really push into the seat acceleration I'm after rather than the sensation of speed. Maybe I should race 1/4 miles in something purpose built.

I can see Fen and Brett talking about NOS kits etc.
 
I missed all the NOS talk.

I like your definition re: breathing. That's what I want; either it accelerates too fast to breath or too fast to retain bowel control [:D]
 
Hi Paul,
it would lock the rear wheels when you changed down even when you matched the revs
I'm a bit baffled, is this actually true or just a throw away comment, why would the wheels lock if the revs have been matched to road speed.

Cheers,
Stuart.
 
Otherwise get a good chip, fix your brakes, upgrade your suspension, get a dual port wastegate, boost controller and have some cheaper fun. Afterall that is why we bought these cars in the first place.

Yup, thats me. Better suspension and brakes is worth say 50 bhp on track and another 50 ish will do me, however I feel a bigger turbo will increase torque??


I agree you don't need a rebuild to go for the minor gains up to 300bhp or so - they're easy to get and you can do it on the original fuel and turbo components. Going much further is a different story though as you increase the stress on anything worn or weak for any reason and you also accelerate future wear on something already worn.

Ditto comment above.

Under heavy braking when I matched the revs as the engine dropped into max torque area the engine braking started to lock the wheels [:eek:] the brakes were perfectly balanced so I know it was not over braked on the rears BUT it could have been a weight thing as mine was one of only two G27`s that had a V8 shoe horned in, the cars that were designed for the V8, the G33`s, were a bigger more weighty and ponderous car.

If I had known then what I know now I could have just bought a decent 2nd hand GT3 and be done with it. [:eek:][:eek:][:eek:][:D]

Except that for instance my car has similar power and lots more torque than a GT3 plus equal weight front and rear. Brake and suspension upgrades on a GT3 are more expensive than on a 944 and engine upgrades would be very pricey. I would hope that for the price of a 2nd hand GT3 you could have a very special 944 indeed.

Of course when it came to selling the GT3 would be easier to move on - funny old world ;)

Its interesting to put some of these upgrades into perspective - for example: good tyres will take 6 seconds off a flying lap at Castle Combe. 100+ bhp made a difference of only 3 seconds (on a 944 Turbo) at the same circuit. Tyres cost less than £600, +100bhp on a 310bhp 944 Turbo - a little more! ;-)

Andrew

I expect my engines to last longer than 3 or 4 trackdays though ;)

The GT3 doesn't do it for me- Possibly the GT3 RS, but not the cooking version. I genuinely would buy an M3 CSL before one in fact.

Maybe you needed to experience it on a winding B-road in the wet rather than the uber smooth roads around silverstone ;)

Funnily enough in isolation my car doesnt feel that quick (though stepping into it after 3 weeks in a diesel Patrol helps) but when you look at the way you can pass long lines of traffic or mix it with superbikes and supercars it must be. I think its because its so capable you have to be accelerating up to 150 or approaching a solid object to realise you are really moving.

How about a GT2? they were almost tempting a while back, the OPC network had a dark blue (3yo) one with slightly dodgy history at £50k was almost tempted as I thought it would hold its money from there, but even at todays prices an extra bedroom is cheaper than that ;)

Hi All,
It is important to understand where the peak torque occurs. I can use my own car as an example. Peak torque on my car appears about 1000 rpm lower down compared to Mark K's. Mark K's car makes maximum torque at about 5,000 rpm which is where you need it for the fastest acceleration - this is one of the reasons why his car accelerates so quickly. [:)]

Regards,
Andrew

I am not sure I agree with this :- if you had no torque at 4500 rpm and then peak at 5,000 of say 450ftlbs and then none at 5,100 you would need an automatic gearbox to gain any benefit.
To accelarate quickly you need a torque curve that is closer to being flat across the engine range you want to work in - decided by the gearing and max revs you are going to run the engine to.
To feel like you are going quickly you can be flat off boost and then ramp up to higher levels giving you a kick in the back old school turbo stylee, unfortunately you will by now be playing catch up with those who started accelerating sooner. Admitedly on track you are less likely to drop down the revs but unless you are customizing your gearing for each circuit you still may suffer in some corners.

400rwhp at what RPM? Please say, well under 6800rpms..

Is there a cam included in the kit?

graphs should be here http://www.cannell.co.uk/944%20UK%20League.htm but they are not they show the previous year when it was much closer to standard (and leaking boost) Rick? just noticed the hit counter is on 944,xxx - nice ;)

no graphs here either (as far as I can see) though there is a pic of Marks lovely car http://www.promaxmotorsport.com/ click on level 4 I also note there is no boost level indicated where it says they will verify the 400BHP.

Tony

Ps is the polished finished standard or extra?

I did experience it on the road - windy and wet quite often. I did 5,000 miles in it between August and May and only 2 track sessions, one of which was an evening where I started late and was black flagged for noise so finished early.

What I want is something that feels fast with no frame of reference - it's push in the back I'm after not overtaking punch or reeeling corners in quickly.

I wasn't comfortable with the assertion it's power rather than torque you need on track, but when I started to reply my head began to hurt.
