3.2 First Impressions

I went down to Jon Mitchell's garage today to drop off the V5 so that the car could be taxed (was a slight oversight previously) and begin its running in. Whilst I was there Jon kindly offered me the chance as its owner to be the first person to drive the 3.2 on the road!

So with zero miles on the engine I got in, with Mark (Jon's son) and a friend who came down with me for company. The car is currently as stated previously not yet connected up to the wastegate fully so we were limited to limp home mode, super safe 0.6bar (or less) max boost and only 4500rpm to run it in with. Jon also had left me with strict instructions to use no more than half throttle.

The first thing I noticed was that I didn't notice any time delay in reaching 30mph even though I had only lifted off the clutch in first and immediately put the car in 2nd it was already idling along at 30. Driving around very slowly at under 50mph in 3rd, 4th ad 5th gears the engine just ran as if idling and didn't seem to notice that it was carrying the weight of three people and a 944 around with it at all. The extra torque even in these circumstances makes a huge difference to the characteristics of the cars driving.

Then after a couple of minutes Mark commented that I was probably taking it a bit too easy and I should just try to give it a little throttle at sensible rpms to work the engine a bit. Obviously given the engines current state of tune I wasn't expecting an example of what the car could do but I was keen to feel the torque that would be available during my first 1000 miles so I obeyed, indicated to change lanes and gave the throttle a light squeeze.. unbelievably I cannot sum up the words to describe my under-estimation of the acceleration this would cause! From a rolling start of 30mph in third gear the car just immediately took off, threw us all back into the seats and went like a jet engine that had just hit afterburner! No lag just a split second of normal acceleration then WALLOP instant power! It took me so by surprise that in the time it took for this signal to reach my brain and my leg to retract we had already hit 70mph! It felt like half a second, or maybe less!! After the swearing and nervous laughter had subsided inside the car I very gently squeezed the throttle again and tried to see how it reacted in other gears. Every time regardless of which gear the now redundant gear stick was in it just went and went fast really really fast!

The G-force is quite honestly like nothing I have ever experienced, Mark instantly forgave the car for all the hours he had spent under its bonnet and my friend who came along for the ride simply could not believe what he was seeing! A car running in, on almost no boost and at low revs was not just marginally faster but in a different league to his golf gti which is mildly spiced up and produces 230bhp!

Specification wise my car is almost identical to Paul's except for the exhaust and after the way Paul's engine spun up its turbo Jon understandably decided to try a bigger turbo 2nd time round but shockingly even with its gigantic turbo (about the size of the LR 75) it still hasn't stopped the engine spinning it up like a diesel! It produces boost at almost idle even in 1st gear!

Since I have returned home (after ringing Jon to make sure the car was not somehow running at 35psi! ..he obviously confirmed it wasn't and that yes it really was just that fast!!) I had some time to think about the whole experience and I think realistically the shock is not at the force of acceleration (which is still colossal) but that it is just available immediately, in any gear, any time and seemingly any revs. It may look like a 944 engine and it may sound like a 944 but really it's just pretending because it drives like a whole different animal it feels more like the mk5 golf Gti! ...It drives like a car with a tiny turbo just with the G-force (Go-force) usually associated in the brain with high revs and a much bigger turbo!

Today also made me realise just how restrained Paul was really being when he took me out for a spin all those months ago! I naturally assumed he was driving quite hard to accelarate they way he did but I now realise he must have been literally tickling the throttle (to use the same exression as the writter from 911 Porsche world) probably to avoid spinning the wheels.

Lastly I would like to say a HUGE thankyou to Jon because after such a long time trying to get my car back almost anything he could have produced would have felt like an anti climax and a dissapointment when compared to what I'd put in mentaly, physically and finacially but today was like nothing I could ever have expected! It's all very well reading the figures but nothing can really prepare you for the shove in the back that you actually get from power delivery like that! It just re-defines my metal perception of quick! I cannot wait to get the car to a dyno and see what its actually producing because if this is its low boost performance DEAR GOD! Is it going to be serious!

My mission now is to take this car everywhere and try to share the experience I have just had with as many people as I can! Jon's magnificent creation is something that everyone needs to experience at least once in thier lives!

Regards,

Ben
 
Heh heh heh - the fun starts here for you Ben [:D] Fantastic news

I'm glad Jon has partially disconnected the wastegate because if it's anything like mine it will be so hard to drive it off boost whilst running in. You find yourself backing off the throttle all the time to keep it below boost level. At least you can play with the throttle a little bit.

Is the car back in Northampton now, we need to see pictures and a full run down of what you have uder the bonnet and don't forget I'm home all weekend if you need to come round and make me jealous [;)]

Everyone else better enjoy the comparative saftey of our roads before you're allowed full boost [:eek:]
 
Wow after reading that I really want one now. I think you're going to really enjoy that when it's run in. Does anyone have any ideas of how much power the turbos with 3.2 are running at?
 
Well mine hadn't been fully tuned before I broke it [8|] and was dyno'd at 393bhp and 480lbft at 17psi boost. I think Bens will have significantly higher peak figures because his turbo is specced for power whereas mine was specced for quick spooling and big torque.
 
Wow, the more I read about these 3 litre and 3.2 litre rebuilds the more appealing they sound. After taking my car for a spin in the nice weather yestersday and even though I was taking it easy because I had my little un in the car with me I was still amazed at the sheer performance so these 3.2ltr rebuilds must be just in a whole other league. I can't imagine it.

Ben, i'm lad to hear you are chuffed to bits with it so far even with only a fraction of its potential released. Now all that is left is for me to find last nights lottery ticket!!
 
Yes, it has the cylinders completely machined away and then replaced with liners to make whatever capacity you like (I believe 3.4L is the theoretical limit for a turbo car, more for a N/A [:eek:])

Great news Ben. I look forward to hearing of your progress, especially when you can wind up the boost and see some numbers. Reading what you've written reminded me of my first impressions of my 3.0L and all that 'oomph' from the extra capacity. You'll have hours of fun with it now. Have you done any head/cam/inlet mods to capitalise on all the extra grunt it's going to have with the big turbo? What about exhaust?
Keep us posted.
 
Knowing what mine is like in the wet/cold when the boost comes in (LSD means both wheels spin up[:D]), all I keep thinking is traction control, traction control, traction control!!![:D]

Major respect is due[:)] Now when's that ISA due up.....?!![;)]
 
Cheers for first comments I'm still smiling from the whole experience. I think the biggest differnece with the extra capacity is the way it comes on boost.. as has been said the standard car tends to come in late with a jerk that spins the wheels whereas hopefully with the way the power comes on so early and really is accelerating hard from almost idle (almost exactly like driving the standard car but with the idle set to 3500rpm[:D]) it should be slightly easier to moderate once I get used to backing off the throttle as a quick reflex as soon as you feel that wave of boost coming. That said though it was still an almighty hammer blow in the back and I think if it hadn't have been bone dry it would just have spun the wheels violently!

As for the head mods yes it has everything in the way of polishing and porting (2.7 head so bigger oval inlet holes anyway) and the inlet manifold has been polished and bored to match the head. Current exhaust is a temporary 2 3/4 inch job which doesn't feel like a restriction yet but will definately need changing as soon as its running proper boost!

Regards,

Ben
 
Ben, does it still have the bonnet bulge and bright red leather seats!? Can't wait to see it... It has my fave colour combination! Best of luck with your recovery and subsequent running in of the beast. Take it steady!!
 
Oooh I'd forgotten about the bonnet bulge :ROFLMAO:

Worth an extra 20bhp but the extra drag negates the effect [;)]
 
How much does that cost!?! In fact im probably best not knowing, ive already been looking at the V8s on the Renegade Hybrid site and thinking that wasnt too expensive.....
 
...Unfortunately, I do! I was wondering exacty the same because whilst using a Porsche engine would be great, I think for similar power, a much better noise and probably better reliability, wouldn't an LS1 be cheaper overall? When my car was in at Promax, they lent me a supercharged Monaro for a couple of days - what an awesome engine! If I could get that in my 944 for under 5k then I'll be selling various body parts!
 
And here beginneth the Renegade Hybrids discussion ...

It's kinda tempting, isn't it? Cheap power, lighter weight, great noise, fun for all the family. Buy a lux with a stuffed engine and a RH kit, LS1, and away you go.

Part of me (the purist, that forced me to buy the 'nice-girl-next-door' S2) says "Oh no, shocking, keep it in the family, that is vandalism of a lovely German car".

Another part of me thinks "Bring it on!"

I've yet to see one in the tin, or even know of anyone who has one, but I'd quite like to see ... and play ...

Which is when the nice girl next doors leaves you and you end up with a dirty stop out...
