Obviously needs more fuel as once its on puff its clean as a whistle but it was left how I drive it daily for a baseline. Well impressed with how the torque just monster climbs after 1,400 rpm.

168 hp / 242ftlb
24psi peak

Definitely needs head flow work, winding up the boost would make more power, but it just heats everything to shit and boils over, it shouldnt be needed from that blower, happy with that result, gti6 power but a shit ton more torque. Will get it dyno'd again after heads been off and played with.

Dont really know what the fucks going on just after 5k, I think its the govnor spring breaking free and then bouncing back again, probably shim it up abit more.

On a side note my mate radiationbeta was there too.. he ran 124hp/197ftlb which I thought was very impressive for a reamed T2/9mm on top mount.

[Mattcheese31]

nice result for yours Dave, dunno about radiationbeta's, it's ok like but i've made 133.7bhp on a K14 on top mount . .

[Dave]

Cheers Matt, I thought 124 was pretty good lol, I guess it must vary from dyno to dyno. Its 9mm with 1.6 bar.

[zx_volcane]

Looking good, where was this done? I fancy getting the zx on the rollers...

[CJ_Derv]

Louis123 made 127 on a lucas and K14 at pod this year when i tweaked it up a tad but cracking results there dave impressed with that torque im considering some head work on me spare youll have to put some piccies of what you do to it i did one on the blaze and noticed a diff but never got chance to dyno as got wrote off

When you hitting full boost in the rev range?

Nice result there Dave, loving the time lapse video

Was at dynodaze in Hinckley, £30 for 2 runs, just turn up wednesday night.

Cheers mate the peak isnt that great but the escalation of it I was quite impressed with. I will try put some pics up, I honed out the exhaust and intake ports what did you do to your blaze? Boost is full by about 2400, would be full wack at about 2.1k but the MBC is abit dickish and seeps a little, this does help surging low down though so i'm gonna leave it.

Cheers bud, hopefully be doing some more work/timelapsing soon as its only a stock engine, needs some better components another reason why im afraid to push the fuelling too much... stock rods are holding out but my parents have been very forgiving recently with the current garage state, dont want to have to pull another block!

[Matty]

Woah, ain't been here in a while.

Any who, I love coal <3 Got covered in it...

yeah probs, it's a proper place we use round my end that maps cars, not a fairground ride style one lol . . . . . what's 1.6 bar? about 18psi or summit? mine's at 24psi . .i would like a bit more torque though, maybe time to lose the middle box . .

[Dave]

Cheers Matty for the vid you ledge, sound does not do it justice (even though I think it sounded 100000x better with the T28 anyway!)

Mr cheese 1.6 bar is like 23psi I think, bout what mine was running.

[Matty]

Agreed, sound doesn't do it justice what so ever. T28 was awesome, but this by far, is so much better when you took me for a spin in it. T28 was so laggy, where from memory, this starts spooling well before 2k and peaked just under 2.4k at 25psi. Loved it.

ahh ok, my head only works in psi lol . . . . .well just goes to show as i've suspected for a while that the K14 is the superior snail, only failing is it's shitty wastegate . . . . .your car goes real well though mate anyway, right animal . .

[kernow_joe]

so what turbo are you running now then dave? not a man sized one any more?

nice result on the dyno whatever you're running!

[CJ_Derv]

I think i need to fiddle with the LDA maybe get fuel coming in bit lower boost to get turbo going bit quiker maybe, i really need to look into puimp tuning in more detail lol ive just done a quick play with it and seems rapid but i no theres much more potential

sounds good, prob give this a go in the next week or so

Let me know if you head down, I'll turn up and spectate!

[Dave]

Bout time I manned up and started pulling the block on the black chariot...

back in the kennel where it belongs



Not much of an update, but will try and get destructo pics up when I pull block/have a look inside at messy goodness.

[Jtrigga]

Seen more pictures of it in your garage than on the road lol

Thats the way it should be! The road is just for learning and diagnostics

Haha your the one that should know that best.

[darrenjlobb]

I also love the tractor battery to one side, just waiting for abuse on leads wen engine goes back in lol standard derv head situation

[Dave]

Just an update, drank some monster energy, manned up and stripped down the block to be sent off for some destructive testing!























Suprisingly light when everything is out of them!

[Sambarker]

Which rods were these? #pleasesaystock

[zx_volcane]

Did you drink the bottle of crisp n dry too?

As cool as destruction photos are, hope you never have to see another hole in a block again.

[Dave]

Sam was a stock dhy motor, so enevitable with 35lb of boost ... The crisp and dry bottles I used to hold onto bolts really. Hopefully won't blow another block as you say, should be the last time I'm pissing about picking shards of metal off the floor.

[strictly_perv]

So what have you got planned for the next build? Forged rods and updated bolts?

[Dave]

Well I thought about just getting another stock block, fitting some hdi rods, and running it as a reliable 170hp daily, as I have the same 2052V turbo ruan had before - and have uprated headstuds too so there wouldnt be an issue with reliability then... but don't think I could take a step down on power now.

[mr_fish]

impressive destruction there!
