So my 044 pump gave up a month back and i decided to go with the Walbro 416 as i can do two if i ever need more fuel. For now i have modified my old basket to fit the walbro .. purchased a rubber sleeve to help keep it put and with the top piece snapped on its not going anywhere. I did a quick ...

Whelp the after the freshly rebuilt engine got broke in and i started turning up the boost E85 here in arizona changed to e55 ethanol so i pulled timing/boost and fuel for a get around town tune and basically stopped driving the car. fast forward a few months and i took the time to relay the fuel ...

Whohoo it starts and sounds great !! And as a bonus i got my B8 back from the body shop today after someone drove into me in a parking lot

That's a good feeling for sure!

Out of curiosity, what was the turnaround time from Jeff?

It was a few months but i had told Jeff that there is not a big hurry... FWIW most of the time was spent waiting on pistons and other parts

That's all understandable, and still a deadly turnaround time ...

Whelp the engine is back in my garage after a visit to FRP (Jeff Gerner) for a rebuild which included new pistons and another head. Need to order some harware before i put it back in

Looks like oil in the intake track may have also played a part as my catch can overfilled and dumped back into the intake track. It also appears that the intercooler may not be getting enough air with the new front bumper. IAT was a bit elevated and so was EGT esp for run 4.

Run 4 was the one ...

It's definately detonation but mostly the head material stuck to the piston... also the exhaust side of the piston is out of shape

Should be fixed now... they went into the wrong album

Whelp theres your problem!... Looks like i will need a new head and some pistons :

I don't think its an injector ... i had a misfire earlier in the day and started to melt a plug for #4. I changed all my plugs, pulled the boost down to spring pressure was runing .85 lambda.. hooked the N75 back up with lowered PWM values and ran a 1/2 and my lambda was .85 to .83 hank had said ...

Yes 88% tested before the event ... most of the time around here its down in the high 70's so that may have contributed to my problem

Great day out at #noflyzonearizona today Videos and damage assessment coming but i melted a plug and have zero compression in cyl #3 ... I have a log of the event but my laptop is doing greater things this weekend

Fresh paint!

Actually enough of the core and support is still there and the FMIC does a good job of holding things in place ... i will reinforce if i start seeing any movement

Lots of grinding and melting but I am close to calling it do-able

Update on my oil cooler. Finished the metal portion of my cowls the plan is to attach rubber to the bottom of each to seal against the belly pan. I added a 6.5" fan to the oil cooler and it seems to really suck Little bit more trimming to do but hopefully it makes a big difference on the track and ...

yup pulled from a f430 but the same calipers that are on the v10 r8's. The bracket is a one off that i made with a local shop... IPSCO was supposidly designing some but i havn't heard any more on that... i plan to pull mine and have them redone one day hopefully that will produce a cad or ...

hard to say but its more noticeable in taller gears... fuel pressure is CH5 in my vemslog

My car has the same lean spike/rich map area around there, plus or minus a few hundred RPM. It may be some kind of harmonic intake or exhaust resonance? A fuel pressure gauge would show if it's a fuel system issue.

I hooked an oscilloscope up to my fuel pressure sensor yesterday to confirm ...

so from the VEMS facebook post it looks like it may be harmonics in the fuel system that i need to deal with... i know my lines are not running optimally so i might have to redesign that In other news i moved my oil cooler to the other side of the car, now working on cowling for both the cooler and ...

So i am trying to figure out why my car needs so much fuel in one band around 2600 rpm's. Anyone ever run into this before and should i look somewhere else in VEMS.
