Lucky #13...Back in the saddle....92 rt/tt

whatever is cheap and will hold 100more whp/tq you want to make gets my vote, also strokers for street cars!

[niterydr]

I just realized I didn't post the "progress" charts...

The 9b's are probably cores now which sucks because we spiked over 26.5psi out of them! (hit fuel cut at 26 psi @3500 or so). Still only 14psi or so at redline, but had a good area under the curve.
22psi to 14psi = 348hp/422tq
25.8psi to 14psi = 368hp/480tq
24.5psi to 14psi = 345hp/455tq


Green pull was "close enough" at 21psi spike-14 to redline. Wanted to leave some on the table. Then we decided to turn it up to an all boost setting (ramp it up fast), which is the blue graph. Timing is VERY conservative on that pull under higher boost, as we had not ventured that high yet in the map.

Car started to misfire at 6100rpm, so we shut down. The power dip wasn't to concerning as we had pulled some timing for safety and figured it would be down on power, the misfire was a bit concerning, hence the shutdown. Checked the car over and it seemed okay, so we figured the misfire was from the lack of timing we added back the timing that worked, see the red graph.

When the car nosed off again up top, something was not right obviously.

We didn't hear much noise (sounded like Throw-out bearing chatter) so did another quick pull starting at 3000, 4300rpm hits, BOOM, smoke screen, car noses over, clutch in, coast to the side of the road. car is still running but sounds like a bag of marbles in a washing machine, shut it down and coast to the side of the road.


My analysis:
Odds are the damage was done @5100rpm on the red pull when it nosed over. Technically it could have actually happened around 5900rpm on the pull before, but I just can't believe that the car made one last go at it and made similar if not more power on the red pull (until it nosed off).

Spun the bearing there and dropped out the cylinder (red graph), next pull was just icing on the death cake. Should have just called it when we heard the chatter instead of assuming it was the loose TOB (weak slave cylinder), 155,800 miles on it with an unknown history=shit happens.

I will have to tear this one down to see what happened. E-85 doesn't show knock on the AEM really. However this motor was quieter from a knock noise standpoint compared to most 3/s I see (pump or E-85, under 1V). When the motor let go, it hit 4V. End of the red pull it was 2V or so....I really really don't think it was detonating, but the motor will tell the story.

Drained the oil today, first thing out was about a 1/2-1 gallon of coolant...that isn't good.

Poked around in the oil pan holes, found a chunk of rod, looked at the rear hole (Now that it is lifted up), GIANT hole in the block.

I don't really give a rip about the 2 bolt shortblock, just hope the heads are fine as those can get spendy.

Ordered a forged crank that should only need a micropolish and have a line on a 4 bolt block.

Also have a line on forged rods, waiting on a piston quote, and found a TD05 14B kit (7cm housings).

[niterydr]

Forged rods ordered with ARP2000 fasteners.

Old school Titan 14b kit ordered. Features twin 14b's with Forced Performance 7cm housings (ported), Titan bending "old school" manifolds and 02 housings, and a 4" outlet downpipe. (bit overkill but eh, I'll run 4" to twin 3" catback mufflers).

6g72 shortblock core
6g72 balance/polish crank
6g72 oil pan
6g72 cp pistons
OEM rebuild gasket kit
oem oil pump
OEM head bolts
Oem main bolts
Oil cooler setup
ACL Bearings
machine work

is the rest of the setup, needs to be ordered/sourced. Also looking at a 4-bolt block on Sunday.

[niterydr]

Update:

14b kit is canceled, guy backed out on the deal and now wants more than I want to pay for them.

So we are back to 13T's (WRX Turbo's) 2 turbos have been located (well 4, picking the best deal of the 2) and already machined housings, so the car is now back to "stock appearing".

6g72 shortblock core -Purchased and arrived
6g72 balance/polish crank -purchased and arrived
6g72 Forged Rods with ARP2000 bolts -purchased and arrived
6g72 oil pan -on the way
6g72 cp pistons -haven't ordered

damn dude, looks like you might have this beast back in time for PG!

You could rock SA/U with that setup!

No way in hell, hoping to get to the track before end of season. There is always the 5th annual MAP proving grounds.

I am swamped with customer work and then going on Vacation from June 8th thru June 17th, so its not happening. However John's Galant is looking like it is on progress

[turbotalon1g]

Nice, yeah I know that feeling if i make it this year it will be my first racing there.

[niterydr]

Oil pan in-route, looking at a block on Sunday if it checks out, ordering pistons.

Woot! Do some junkyard diving or find one already out and ready for ya?

Hard to find the 4 bolt forged stuff in the junkyards. Picked up a shortblock locally that was a garage paperweight and a crank that was serving the same function in Tennessee.

Rods arrived last week, need to measure block to order pistons. Then its an small overbore and some parts away (bearings/new rod bolts/seals/gaskets) from a functioning shortblock.

Plan on pulling the motor after the proving grounds, should have everything else here or damn near here by then (turbo's included). Hopefully have it up and going for early August action.


Motor should be good for 700+AWHP as is similar build to my previous motor I had in the blue stealth (short-block wise) while the turbo's....we'll try to squeeze 500 out of them, its been done before on E-85 and piggybacks with 21psi of boost.

[turbotalon1g]

That's gonna be sick I remember that powerband of the 13Ts

Good, one more person is just as far along as I am.

I'm shooting for track ready in August, break in/street/dyno in July, all hands on deck for John's Galant until after the proving grounds.

And before that bundle of joy comes and the moontaxi gets parked!

[Halon]

Awesome man, keep going and git r done!

[turbotalon1g]

we will have to plan a group trip to the track come sept./oct.

I like it, call it the "I wanted to race this year, but instead get to race 1 time before winter" event.

Update:

Car has been sitting essentially since May. Except for pulling a few parts to help locals diagnose issues on their cars it hasn't been touched. Still awaiting to pull the trigger on .020" overbore pistons through MAP, hope my quote from a few months ago is still good.

Once pistons are ordered machine work on the block can begin with assembly. Plan hasn't changed much, Forged shortblock good for 700awhp backing up a set of newish 13t's (WRX Turbo's). The record for these turbos on E-85 is 501awhp on a mustang dyno with piggybacks, I'd like to break that, but the car will make what it makes. I figure around 400 on pump gas is attainable with the setup and 450+ on E-85 should make a stout street car.

Bought a boat this summer and the wife a new car last week has put this car on the backburner. Plus with us house shopping it is even lower priority, but I do fully intend on having it on the street next spring. I'd like to rebuild the transmission, add a brace, and swap in shorter gears ala what Ryan did with his Green car, but time will tell.

[Goat Blower]

Buying a boat this summer? Fall is upon us my friend, but I will put in a shameless plug because I'm selling a boat.
