Finished!! Forged piston block, Custom valve head (flowbenched)

[Ondonti]

Did a compression test on #4 just be be safe. Still 120psi (good).

#4 and #6 still want to foul out when I was troubleshooting last night and I spent a bunch of time on the wiring using liquid tape to help insulate the wires (had goopy tape on their before and well it didnt work so good) so I am going to try different injectors on #4 and #6 (i have 8 30# injectors so I have 2 spares)

Pretty sure that what is really wrong with my shifting is the pressure plate. When I did a 1-2-1 shift 2 track visits ago, I probably damaged the straps on the pressure plate so the center friction surface is no longer centered properly. Reason why this was not obvious to figure out is that I never did a high rpm shift EVER on that transmission (temporary replacement) or clutch (new 3 puck disc) until i was at the track. I think that my 1-2 was a successful high rpm shift because the slicks were spinning in 2nd gear the moment I shifted (not hooking up so great). Its all very foggy what happened on that run because I was more interested in the miss-shift then what had happened previously.

I went shopping for one today on the internet.Interesting to note because I didnt remember...that the T1 and 3.0 Pressure plates's are the same.

TII and TIII PP's are a different part number (stronger also).

So I am getting a clutchnet 2x TIII pressure plate ( I would have mistakenly ordered a weaker 3.0 pressure plate).
Basically they modify it by machining the lever point on the friction surface so it is closer the the pivot point

This gives more clamping force

According to the guy I called, its +40% give or take.
So this is basically a replacement for my Sachs pressure plate from Eurodrive that I damaged.

I did NOT want to go with a dual diaphram pressure plate from FWDP or TU because they have less clamping force (about 2100 compared to 2400) and they require MORE pedal effort then the single diaphragm pressure plate I am buying which holds stronger!!!!!

I have already had a pressure plate like this one and I like it so I feel good about buying this. I was stressing out while "shopping" because I like what I have and TD vendors dont seem to sell strong single diaphragm pressure plates unless you want a $300+ spec unit which I have never seen a picture of before and I almost bet it is the same as I am buying (stock t3 modded to hold more) but with the spec name.

im liking the stuff clutch net has to offer. i think il order from them. i really want a aluminum fly wheel too

[irocelectric93]

If i get the iroc on the road again....ever i will def be getting a fidanza flywheel and clutch upgrade.

I just did a little MS homework, found out that I only need to add a jumper from IGN to JS10.

So Bansheenut will do that for me and then its time to play with Megasquirt when i have time.

So I will probably work on this while I am pulling out the motor to swap the pressure plate with my new undamaged one.

I cant wait to try 7000 rpms out :P

[Shadow24V]

lol, keep up the good work brent!

[mopar3.0]

man if i could pull 7000 rpm for autox that would mean less gear changing

[Shadow24V]

im hoping to push 7500 in the 24v

[Ondonti]

Past 7000 I think we will see if stuff starts breaking.

OR if lifters just collapse.
That is one reason to not get stronger springs. Titanium retainers would be nice though. Wish those existed.

[Shadow24V]

IIRC there are some 3G guys running 7250-7500 in boosted applications without touching the valve train really

[Ondonti]

But my valves are larger and heavier then the 24v. The only good thing is that my ferrea valves are about 15% lighter then stock valves.
Titanium retainers would help a little bit too but actually the valve weight difference is pretty huge (like 97 grams stock intake and 82 ferrea intake). Thats a bigger difference then titanium retainers make.

So maybe I can try. My more aggressive cam probably means I cant try to rev much higher though Or that I might get away with some stronger springs considering the lighter valves.

[Shadow24V]

yeah, makes sense if my valves are lighter and all.

Well.. it's been a while so I'm poke this thread with a stick to see how things are going. I read all 1182 posts (Only took like, 5-6 hours).. So... hows the story end.. did you ever meet that LS1 guy?

[Ondonti]

ls1 guy is unhappy with me at the moment
Something about when i damaged the pressure plate at the race track and couldnt shift gears above 3000 rpms he challenged me to a race later when i was back in the parking lot removing my slicks and I told him the car was not shifting (didnt know why yet). I asked him to help me change my tires. He didnt like that and left.

I am currently fixing the intake manifold and I need to swap the pressure plates and reinstall my car gears.

Too busy with school right now to finish the work.

Also getting my megasquirt stuff together as I am not satisfied with how rich the car runs at cruise and idle..and I dont see to be able to lean it out. The mechanical fuel control works fine on a stock motor but its not liking this motor.

I will basically be done with my bachelor degree in December except for 4 credits I will take online so my goal right now is to not screw up my GPA by worrying too much about the car. I already worry about it too much as it is.

[TurboDodgeNoob]

Well, Good luck with all that, just tell us how it ends when it does, dagnabit! :Thumb:
