No real updates for me, I am having a horrible time with the partial throttle tuning on the car and am getting very frustrated with it. Right Now I have the boost set to 33 psi with a conservative 12 degrees of timing up top. VD is giving me 620s at the moment. Nothing to write home about.

Some data thought, my Load did increase slightly at the same boost level, when I went from the ams vsr to f1i. So my assumptions were confirmed when comparing the two.

 

Yea that makes sense. I went with the 22-41 instead as it offers the larger size 16 contacts. Then I am just going to have to delete more stuff ie reverse light switch lol and then running my maf wires with the chassis/light harness it should clear up enough.

 

New connectors came in but I have another question (when will they end )
My concern as I've never used these types of connectors is that the rubber seal on the rear of the connector has an O.D. of about 1.1inches while the I.D. of the backshell is closer to 1" and as a result when carefully tightening it, the rubber begins to distort due to the smaller diameter. I don't have any pins in it yet but I didn't want to ruin the connector by installing the backshell. Is this normal, should there be something between the two? Should the backshell bottom out on the connector?

 

Looks a bit suss, thought about ditching the back shell and going for a shrink boot?

I'm running the Deutsch auto sport connectors and they run shrink boots instead of a back shell which personally I think look nicer, look up raychem shrink boots of hellerman shrink boots.

 

No real updates for me, Still working on the boost and timing curve .. Recent pulls are right around 650Hp and 520TQ with 7 degrees of timing up top.

I have been trying to understand and correlate small incremental steps in timing and how these correlate with an increased/ decreased Torque curve. This is sometimes very frustrating to work with because I feel that this type of testing is better suited to a dyno versus a Roadway..

Someone sent me pictures of a recent car show that I attended. Thank you to the fellow that took these pictures. Notice the Sparktech Covers from Evodan, that I had annodized Black to complete my Ignition set up.

So over the last few weeks I have been doing timing sweeps , air fuel ratio sweeps and boost sweeps, to really check the characteristics of the engine , the efficiency of the set up and just how by manipulating each of these factors, the Torque curve and given output can change.

Here is basically where I am at with the car, 37-38 psi about 12.0 afr and about 7-8 degrees of timing


Whats interesting about the curve above is two fold:
1) 3-4 psi more boost = over 50HP, with only 14TQ gain
2) minimal timing NOT in the peak torque area, was able to sustain this.

Now to the tuners out there, I am surprised by this, because typically one would see about 9HP/psi but this is always in conjunction with increasing the timing in those peak areas too. Interesting stuff

Next, I have been plotting Knock Voltage and Knock sum versus time during the pulls : here are two graphs

This is at 40 psi and 13 degrees of timing ( gave just under 700hp)

Notice the spike, with rather "normal voltage" ?

Now look at this one ( 38 psi, 8 degrees) ( Less load compared to the graph above)


Notice the voltage spike ?

I have definitely learnt something new.
enjoy the data.

 

Looking good so far Warren, what were your VD #s when you ran the times in your sig?

 

Thanks BJ the most I ever saw, was in the High 600s, however the car was about 200 odd pounds heavier at the time. I have not really changed anything on the power side of things since I ran those times, mostly just trying to improve efficiency and longevity of the car.

Honestly If I can be between 140 to 143 mph, I would be very happy. Then it is time to concentrate on the FWD.

P.S I am setting up a grudge race with the colt and my brother driving it.

Here are the stats from VD
EVO information
Weight 3040Ibs ( including driver and fuel)
HP :650
Tire : 255 35 18

Colt Information ( AWD car)
Weight : 2650Ibs ( Includes driver and fuel)
HP : 430
Tire : 26 inch Hoosier QTP

Who do you think will win ?

 

A real interesting read.

 

What kind of money are you racing for?

I have to go with the colt, I have to root for the underdog and because I own one.

 

This was awesome. Reminds me of the first time I ever saw a mil-spec connector like that. I was whipping my CB7 and a guy from the forum did this as well. Still amazing and insane and beautiful all at the same time... I just cried a little. Don't judge me lol

 

Rough weekend, and it would seem that luck is never on my side.

We decided to go to No ET for some passes with the colt and the evo. Unfortunately the oil filter came loose during the pass, causing 5.5 quarts of oil to evacuated from my engine rather quickly. It was kind of scary on the big end, because basically the oil was going under the front and rear tire, which caused me to counter steer a little as I slowed down.

The cause of failure is due to the burnout, which probably had a lot of harmonics in it, that caused the tight oil filter to come loose. Next engine I will safety wire the filter.

Pictures of the mess basically the entire side of the car is covered in oil






My wonderful wife helped clean this pile at the car wash and I am glad I did it, because it would have been awefully messy trying to do it in my driveway.

Thanks jeremy and Kevin for helping pulling the motor yesterday. Due to all of the wire tucking etc, we were able to pull everything just under 2.5 hours.
the queen has returned to her throne



Tonight after work, we will tear it down, and see whats needed to rebuild it again.



1.5 Months to the shootout, This is an unfortunate and unlucky thing that happened to the car, but that is racing.

more to come

 

Damn Warren, sorry to hear that! Good luck with the rebuild, hopefully the motor won't need much!

 

That is ****ty. I have yet to see a safety wired oil filter I like that idea. Just don't know what that would look like. I would think if u punctured the outside of the filter you would create a leak. Good luck with the findings

 

I hoping that it is just bearings, as I shut the engine off quickly, but I will have a better idea tonight

If you buy the filters that have portion on the bottom to attach a socket, then you can drill a hole in there without impacting the filters integrity. There are other ways to keep it secure and not allow it to twist as well.
