2008cc 8.75:1 CR 3A G60 build.

IT"S ALIVE! Phew! Thanks God. Don't feel any faster and EGT's seem ok! Really tappety when I started it and took ages to quiet down but it fire on the first attempt this time. I set the timing up and took it out for a blast. Pissing down with rain so last traction in 2nd at FT easily.

We shall see on the 16th!

Manifold pressure has dropped from 0.75 bar to 0.6 bar. Or 10.9 psi to 8.7 psi. So it's swallowing more air again. Time for a 3.5 fpr and some bigger injectors let's see what Wayne can do! Looking forward to driving it all next week.

Things I need or need to do:-

1. An ABF headgaset! - ordered n paid for X2
2. G60 8v Exhaust gaskets - ordered n paid for X2
3. Gonna make another custom matched intake gasket for future reference. - ordered n paid for
4. Coolant take off gaskets n seals - ordered n paid for
5. Decide whether to go with the lucas/denso type disc injectors I have and if so get them tested. Or get bosch greentype or the new type 3's, can't decide! Going with the Lucas injectors untested Nope going with 3.5bar fpr and saab 350cc's Tested!
6. Sort out the bottom end breathing which is currently as standard. No time!
7. Throttle body Gasket - ordered n paid for
8. New u-bend boost pipe - £100+ not going to happen, current one will hold for now.
9. Possibly a new distributor just incase it is inaccurate. - £80 not going to happen
10. What ever else I've forgotten! Oh yeah make some time and think of an excuse to tell the missus for me messing around with my car again! Errr been hard work the last few weeks trying to explain the problem!
11. Head Bolts - ordered n paid for HAHA YEAH RIIGHT!!
12. Fit Head X3 Thank God
13. Get mapped

those map values are on a par with what I was seeing with the 16v head.

Anyway great to hear that it's moving under its own steam again.

Now, that IS interesting! And indeed shows what an 8v can do. I wonder what sort of MAP values a CNC head gives? I bet they aren't that good.

I know! If I can make 230bhp at the wheels (DIN) and increase torque from 210 (DIN) to around 220-225 DIN I 'll be satisfied with that. Fingers Crossed.

It's my Birthday on the 13th so it will make a lovely late b'day present! I'm 38!

The CNC is good on paper but it's exhaust figures just aren't that good. JP sent me CNC flow figures and it doesn't matter how well the intake flows if the engine cannot get rid of the gasses it's all for nothing. This head has been ported back to front meaning the exhaust was taken to the max and then the intake was ported to match the flow of the exhaust. This achieves maximum air speed and flow efficiency ie. What goes in comes out again without robbing crank power pushing out the gasses.

I know! And it's a lower value than when berno (9.4 psi) had his engine mapped at stealth with at 229bhp wheel power. Thats was with a standard charger 65mm pulley ribbed and g-werks maifold. So If I can make 230bhp at the wheels (DIN) and increase torque from 210 (DIN) to around 220-225 DIN I 'll be satisfied with that. Fingers Crossed.

Fingers x'd for you too mate.
I think you should be able to match those power levels if not the torque with all that compression he was running,although saying that it might be offset as you should get a torque hike with less pumping losses.
We shall see.I know that you have been coerced by Kev and the 6 cylinder Boost crew
so it will be nice to see this last little ode to the g60 make the numbers.

On a slight tangent,I was in my office today and a golf went passed ,obviously a VR.My young work colleague looked at me with a confused look on his face.
He said"That was a Golf".
I said "Yeah".
He said "it sounded really fruity".

The VR engine nose sounds even more bizarre coming out of a bog standard MK3 golf.That noise sounds like it should be emanating out of something a lot more exotic.

Oh I really want to stick a 62mm on it just out of curiosity see what the boost does.

Hoping to relocate the business before new year so I'll be walking to work so I won't be doing a lot of miles in it!

Does "The other" 2.0 litre g60 use a 62mm pulley?

You need help mate.

You should work from home mate.
Job done.

Yep 62mm, those top 2 engine's in the vortex top 20 thread run 62mm although they do rev them to 7000rpm with a wild cam!! Hmmm. If I break it during the remap I could always use the other charger to get home!

OK I've calmed down now 65mm is staying. Phew!

it will be nice to see what the head does on it's own.

Yep, plus I'm broke and just have enough for the remap at the moment! Gonna have to take a sabbatical on this obsession!

Did I mention one of the speedo wires broke, happening a lot that lately!!

OK really glad I didn't order the 62mm I would never of run it after recent events. This morning I replaced the Lambda with a new bosch item, bloody b'stard to remove, fought me all the way. Then tonight I checked the timing and changed the copot resistance to 500ohms so the remap starts at the correct level rather than 5% co like last time due to the due to the broken lambda signal wire. i'll have him check the co before he starts mapping too if he has one.

Tonight I checked the ignition timing and it was bang on 6˚ at 2k with the temp sender disconnected! That's right isn't it Rob?

Filled the boot with tools and the new fuel items and anything else I could find that was lying around. And all set!

Hope I don't have any issues!

I'm gonna say it will do 220bhp at the wheels and 225lbft at the wheels. If it don't I'm gonna..I'm err well....I'm gonna go home; with my tail between my legs; and be thankful it still works!

good luck mate.
Do you want me to come and sit on the front end?
I'm putting on weight.

Yup 6 deg at 2k with blue thingy dissed.

Thanks Rob. I want 3rd slot on the vwv top20 whp!

what time is the remap?

Starts at 12 but I'll be there around 10 to fit the injectors and FPR! I'd like to pu it on the rollers as it is and see where we are at if he is there and agreeable I will!

the hall of fame.
Actually it is interesting reading those specs.
I wonder how many of those chargers on the 62's are still running?
I bet your still tempted...

damn achilles heel.

The top one I know is in bits. The 2nd one screwed a charger trying to get more at JD Engineering. The 4th is a toothed 65mm so that'll be snapping belts for fun. And the 3rd is questionable the RR through a wobbler at 3000rpm and gave him a figure of 243lbft at the wheels! I don't think so The other 3 runs made peak power alot later in the rev range and not as much.

Non of them are competition really and I'd do well to beat any of them but I like a challenge and I have a full 2ltrs so...!

So.......

So.. it went bad I'm afraid.

I said the car felt the same didn't I after the head was fitted I can also confirm that disconnecting and reconnecting the lambda affects all fueling through out the rev range but the main point is I made no more power infact according to the rollers at chipwizards I could only muster 180bhp at the wheels and 208bhp at the fly so I've lost 20bhp. It doesn't feel like that but there you go. Infact I would go as far as to say if I'm brutally honest with myself my old block and engine felt as powerful and that made 186bhp at the wheels yeah there is more torque but top end, no difference!

This is the end of this thread for the G60 engine I have no will to attempt to improve these results and from recent and historic proof it would appear the G60 does indeed have it's limits both in boost and in power. People have made more but I don't think many are on the road and those that made even more are now in bits.

I'm not pooping the whole engine but I have satisfied my own curiosity fully about the G60 supercharger. Actually thinking of just transferring, when the time comes, everything else less the head and block to J808 to maintain it's originality but I will try out the gearbox I have and see how I get on with that.

The chore and expense of a block and head change to J808 just doesn't seem worth it and it would be nice to keep it's history and originality.

Sorry to disappoint guys, I'm not totally gutted but it has been a bit of a blow after the last months efforts not to mention hassle and expense.

Wayne did say as I was leaving, "Have you thought about fitting a 1.8 20v turbo. good cheap power them!" I had to laugh and agree with him! He did his damnedest to make it work! Cheers Wayne!

Over and out!

I think I'm more disappointed than you.
Hmm.

Not a good week for the g60 then.

dirtytorque wrote:Not a good week for the g60 then.

Nope! Tis disappointing. I think I'm ready to move on to a new project before I get old and bitter.
