Great Success!

[Tom Fenton 1,548]

So I have just heard from a guy who was at the rolling road day I went to on Saturday. He is a pretty serious tuner who used to calibrate rolling roads for a living, and was not entirely convinced about how the tests were being done.

 

Anyway after properly correcting both the stp and removing smoothing from both the run up and coast down numbers, he has found me some more horses!!

 

If it is to be believed, 204bhp and 211ftlb.

 

To quote myself, f'in get in!!

 

Just need to mend it now, shame it wasn't 204.6 as well, because then I could have rounded up to 205!

Well in tom, just goes to show what can be done with a trusty 8v

Nice!

 

Just out of interest/curiosity, what make of rollers were they?

[Stevo309 0]

Superb Tom. Impressive from 1.6. Hope the problem is just head gasket as suspected

[Tom Fenton 1,548]

I'll tear it down later in the week to see what the damage is, fingers crossed! Another guy who was there was running a fresh engine that had been on an engine dyno, he said the rollers were slightly low, but with correction now were close to his engine dyno figures. So I got over the 200 bhp I was hoping for do I'm claiming the headline figures! With the head sorted I'm thnking about the next step to push for 220bhp. I reckon a bit more advance and possibly a tweak of the cam timing will do the business.

Yeah go for it Tom. I'd claim the 200+ bhp too on that basis. I see you updated your signature

Forget 200bhp, the 211lb/ft must make it feel mega quick!? Must struggle for traction in most gears I bet!

[Tom Fenton 1,548]

Yes it really has some shove to it, I kept the 1600 g/box too so it really does romp through the cogs.

Allan had a quick go in it before we went to Germany, his words were that it feels a lot faster than you would expect, and that when it comes fully on boost it has more push than his supercharged Mi16.

In the wet its useless, in the dry with the plate diff it depends largely how you drive it, if you are harsh then it will break traction, even trying to be careful full shove in second will break traction, but with a bit of modulation of the traction control system (my right foot) you can use "most" of it.

Much to my mates disappointment it will absolutely trounce our Mi16 track car on bodies in a straight line, for a lot less time and effort than it took to get the Mi16 car to where it is now.

Tis true, I was incredibly shocked at it's pace, it really does shift. I was expecting it to be like an xu10 turbo but it couldn't be more different. It behaves and sounds exactly like a n/a 1600 up until itcomes on boost and then it really picks it's toes up and it loves to rev! As Tom says I think it pulls harder than mine. once the mappings sorted to give it another 500 rpm or so it'll be an absoloute monster. The 1600 box really makes it for me I'm considering putting one on mine now. I think it's bit of a mosconception that short boxes on boosted cars are useless, for a fun car like toms it's very well suited.

 

Oh and the bloody noise it makes

nice one Tom

 

trusty little 8v turbo

[miamichris 9]

Just saying what everyone else is thinking but...I want a 1600 turbo now

[Stevo309 0]

With the shorter stroke of the 1.6 and that gearbox + torque i can imagine it is very willing to rev and climb through the gears very quickly. I wouldn't mind experiencing it. I remember my 2.0 8V turbo being pretty quick in the 309 but even with the 6 speed box it was quite long in the gears once you were up to 4th and above.

 

I bet it's quicker than my 306 being 300kg lighter as well

Really liked your thinking behind this engine build, Anyone would be over the moon with those results.

 

Well done Tom, I'm quite envious

[pug_ham 245 3 Cars]

Sounds like you've built a nice little sleeper monster here Tom, albeit not n/a you're still breaking the magic 100bhp / litre figure with the torque to match so it really should fly.

 

One thought I've had since this build is about using the 1.9 pistons in a 1.6 to drop the c/r rather than the expense of head modifications but maybe thats for someone else on another build.

 

I drove a GTI for the first time again in almost two months earlier this week & even though it was a 160K+ 1.6 & I didn't really get chance to open her up due to traffic I'm really looking forward to getting mine back on the road with its fresh engine.

 

Shame picking the wrong torque wrench from work has stopped it again.
