good stuff Nik, cute knife. sucks about your cam and it is also some BS that they took the privilege to flow your heads with out consent. that would piss me off.
Those are impressive flow numbers, Nik. I'd let the wait go, in all honesty. That seems to be the status quo for big name companies. HP Performance promised me a turbo kit in 2 months. I got it 6 months later. Fortunately, I knew what I was getting into before I started. I ordered from them because I liked their kits and I was deployed for a year. So the timeframe didn't bother me.
Is there any reason you didnt just order the heads direct from summit? I know its a little late now, but they would have been on your doorstep in 3 days
The retainers is a good selling point. Just be sure to keep an eye on the Ti retainers every couple seasons, they do have a shelf life and the springs will wear grooves into them. I put them on my car last year and there was much more wear than i expected in the short time i ran them when my car left the body shop. I actually went with tool steel retainers with the new cam setup and will see how they work out at 7500rpms. The reason i bought those was they were only like $140 and they are very close in weight to the titanium retainers.
Just sucks you had to wait so long, i would definitly bitch to TEA, and charging you to flow the heads seems bogus to me, it should say that on the website when they quote the price if thats the case. I called them about porting my lower and they never got back to me... luckily the ports matched almost on the money when we were assembling my motor
Well, crap. I had no idea ti had a short lifespan. Meh, whatevs. We'll see what they look like next winter and go from there.
Time for a little update. The parts came in Thursday afternoon.
Well, most of the parts.
I'm not going to say a lot about it, because I'm trying not to dwell on it, but as you guys know, I ordered the parts 5 weeks ago. I was told 2 weeks. To clarify, the heads and intake came in 3 weeks late. The cam, the ONE thing I need to actually make some progress on assembling the engine, is not here yet. Supposed to come in Monday or Tuesday. I'm a little frustrated.
That's been my experience thus far with T.E.A. I can't say anything yet about the quality of their stuff, obviously, as I haven't put it together and ran it. It looks good.
Anyway, below are some pics of the intake and heads. Just as a reminder, the intake is a TFS-R 90mm, CNC port matched to the heads, and the heads are TFS Twisted Wedge CNC 205s, milled to 61cc chambers. Oh, by the way, they flowed the heads (and charged me $50 for it, not sure I asked for that...). Here are the numbers:
Lift - Intake - Exhaust
.100 - 70.70 - 56.90
.200 - 148.9 - 106.8
.300 - 224.4 - 153.0
.400 - 274.0 - 195.8
.500 - 305.7 - 220.2
.550 - 314.7 - 230.8
.600 - 319.3 - 235.8
It doesn't say on the sheet, but I'm assuming that is on a 4" or a 4.030" bore. I have no idea what kind of pipe they ran on the exhaust.
Pics:
Tried to get a shot where you can clearly see the difference in chambers. Notice the shrouding on the stock valves, and also the rotation of the valves on the TWs versus the inline valves on the stock heads.
Stock header gaskets were way too small for the TW exhaust ports. Go figure! So, I'm going to try to trim them up a bit. You guys like my pink Exacto knife?
This is an awesome build im ready to do the same... how much do you think it will all cost said and done?
well we sold our TFS R intake, and going single plane with a GM ls TB like on my 98gt, AND a custom cam.
nik: you will lose a lifter or 2 before you mess up the springs or retainers. if you haven't looked into it yet, I would DEFINITELY get some good ones. We killed i think 3 last year, the stock ones just cant take much more than 7k. It didn't destroy anything, they just come apart and would smoke a pushrod, but it gets old changing them.
Renegade cars have been spinning stock lifters past 8k for years, I plan on going 7500 on stock lifters and when my cam was ground i was told the spring pressures need to be right but it has more to do with the ramp rates on the cam that helps the stock lifter survive
Can't wait to see this bitch put back together!
