blown 944

Patrick,

Have you sourced some E-85 and are you going to dyno it before and aft if you do use it ??

I would be very curious about the results in a back to back comparison.

Well maybe we should have put the KEP II in as it would have exerted greater force than the Blaszak one and made the transition smoother? I'll persist with this one for now. I'm getting the hang of it.
Sid, no E85 just yet. I wasn't planning on doing it with this build, but I might anyway. I think back to back dyno's might be a bit skewed in that they will be different maps and allow different boost levels. I s'pose you could just dyno them at the same boost, but that might not prove anything? Maybe if we can advance the timing it would get on boost earlier, but some have said that they found they retarded timing to get their best tune...not on E85 mind you but some info anyway. I will look into it once we get a few more pressing matters out of the way. I don't even know if it's available yet.

Hey Patrick,

Great to hear you are on the road... finally!

Timing aside, you'd expect a significant increase in power at the same boost level on E85 simply because you'd have more oxygen to burn at the same boost level, albeit with considerably more fuel.

I'll chase them up about the E85 during the week and see what's happening.

When are you expecting the Link?

Another thought re injectors if you are thinking of E85 but want good idle... You have good idle at the moment with your 86? lb injectors. The bigger injectors tend to be lower impedance which means they draw greater current for quicker response time. So, I'm thinking if we check the minimum open time for your current injectors, you can figure that's okay for idle, then check the bigger ones - hopefully, they may have a quicker response time and therefore a lesser minimum open time so it might not be too much of a compromise. Are you running resistors with your current ones? Will the Link allow you to run very low impedance injectors without resistors? This may all have an impact.

Yes of course, you're right there Scott, I didn't really think about that clearly. Comes with not enough sleep.
I'll have to look into the E85 more earnestly with this build as I said before I wasn't really thinking of it for this one, but may as well as Sid's proved it to be such a good platform to build some decent power and cheap.
I've got up to 300km's on the car since last night pickup. It feels nice and solid with plenty of torque of course plus promise of things to come once we can get enough miles under our belts to give it some boost. We must have a 1 bar spring in there as I have the Apexi turned off at the moment and it's still wants to hit 1 bar if I'm not careful. You can feel that the head/cam combo is just pulling at the bit wanting to get into the higher rpms but all in good time.
As there were a few delays with the LINK and some extra components we decided to get the car back on the road with the previous setup which is the Vitesse Stage 5 kit. It loves the extra 500cc's and spools up nicely even on low boost / rpms. Can't wait to get everything all together and finally see what all these great components I've gathered can do. 2 weeks until the first meet of the season. Can't wait!!!!!

Oh, and back to the topic. I am actually starting to really like the clutch. It's kind of like a challenge to get moving as smoothly as possible but then once going you can just shift into the next gear and have virtual immediate response. In other words the play that makes life easier or more pleasant off the mark also seems to slow the response when on the move. With this disc, you just shift and bang you're back into the power. Nice. Also looking forward to some tracktime with this now!

I am pretty busy knocking off these run in miles. Up to 400kms now so that's about 250 out of 300 miles. Then we can play a little. Feels damn strong. Impressed some guy on a big jap bike tonight enough to pull up and ask what the hell car it is. I told him oh it's just a little 4 cylinder Porsche from the 80's, nothing special....

JET951

ha! nothing special, why you kick my dog!

Diver944

Sounds like you need to do a few 6000rpm launches to wear that clutch in

Just kidding, as I know you will be gentle for the break in

Just been out and put on another 260kms on the engine (415 miles now) so we're into the boost pretty much. Need to check out the wastegate or ebc as this thing wants to keep boosting not sure how high. I have had the ebc switched to the off position so far and that just uses the spring. I think it must be a 1 bar spring but it goes past that. When I switched over to my old settings which was set at 1.2bar, it went past on up to 1.4 something so I've switched back to the off position. Er let me tell you that one time it hit 1.4 the car sort of went like a
FREAKING ROCKETMISSILE FROM HELL!!!!!! So we won't go there again just yet. hehe Even at 1 bar it's a very quick machine. I haven't even mashed the pedal to the floor. It just builds boost too quickly before I'm ready for this engine to have yet. This one is a keeper. Can I huh, can I keep it?????

JET951

we might want to check the wastegate lines when you come in on monday too. just to make sure. have you been living in your car Patrick?

evil 944t

Did you take the Corleone school of break in class? If you keep this 1.4bar crap up, we are going to take it away from you! Get some more miles on it!

Good job Sean!

333pg333

Yes Corleone did come to mind. lol No more 1.4 just yet, that was just once by accident...but accidents do happen so the ebc is back in the 'off' position for now. Still 1 bar is pretty nice too.

David Floyd

A block of wood under the go pedal makes for a great boost controller.

Can't wait to hear your thoughts when you open her up !

333pg333

Not such a bad idea David. It really just shot past the 1.25 setting onto 1.45 and I don't think I've yet to really mash the go pedal yet?!?
The head and cam feel like a revelation. I believe that these are a vital modification to really unlock our engines. It feels like a 16v by comparison to the old stock setup.

dand86951

What cam are you using and who did the head for you? Can you share the cam specs?

333pg333

The head/cam/block/inlet/throttlebody etc has all been done through Custom Engineered Performance and Performance Developments. Contact Dave / evil 944t for any details. It's an 8v 2.5L head that has been breathed on along with the race spec cam. The workmanship is top notch. I'm looking forward to the dyno results which I hope to have next week.
