JB Weld finally gives up :)

I did one lower power test pass and ran 10.90 127mph. Then put the full power back in for run 2 and the head gasket blew 900 feet out in a spectacular fashion

The engine made some funny noises so i shut down and coasted to the exit gate in a smokescreen.

She pulled the best she ever has up to the point the gasket popped. My steel implant held up. But cylinder gasses got in between my repair and the liner to blow through to the water way and under my repair out the side of the block !!
The engine stopped itself as I went under the gantry as it was water logged.

The launch had the best power yet which means I will need to tighten up the slapper bars as I got tramping and she tried to steer from the rear like she used to do before the slapper bars.
Watch the vid and check out the ET for a pss with no power for the last 300 feet? I'm well happy with this result. So now its time to put the good block in at last. I will also need to check my engine bay wiring on that side of the engine bay. this will make sense when you see the video

I'll post up pics of the damage later..

OOps, time to get a slipped liner block and fill the block with----errr---Block Filler,
That old engine hasnt done bad for the amount of serious abuse that you have thrown at it.

Hi
I will swear I can see daylight under that left front tyre as you launched, might that effect the directional stability a bit?

Best regards
Mike

LOL - Love it, looks like its steering from the rear nicely

Can only imagine what the start line crew are saying 'oooh hes broken it again'

That old block has done really well considering it should have been scrapped a year ago

There was a bit of an early lunchbreak whilst the crew cleared the track.

It was quite spectacular, the smoke screen at the top end where we were was so big that the only way we knew he crossed the line was when the time flashed up on the gantry.

Nice work Perry, can't wait to see what it'll do with a good block in there........and not so much rear steering.

Looking good Perry

Give us the other numbers, 60 foot, 1/8 et and speed etc.
Be interesting to see the figures for the 10.9 and the eventful run also

First pass was 7.0 to 104.7 at the 1/8th.
Second run was 6.4 to 104.6 at the 1/8th.

She pulled real hard and felt nice up to the point of failure

6.4 at the 1/8 = 9.98 at the 1/4 if all goes well.

So my sub 10.5 pass may not be too far off then ??
And the flat 10 maybe by the end of the year if I'm lucky

What was your 1/8 et when you ran your 10.6 Perry?
I bet it wasnt as good as a 6.4.
If you had just maintained the 104mph through the second 1/8 you would run 10.7.
If it hadnt gone pop then a VERY low 10 was on the cards and maybe that 9.
