Hi all, I've got a 90 lx hatch that I currently have apart to replace a chewed up roller lifter & cam plus some other upgrades.I'm wondering if anyone has tried the Trickflow track Max performance cam & can give any feedback on it? I want better mid & top performance but I still need it to pass smog so I don't want to go too wild. Other upgrades include larger c&l maf 73mm 65 mm TB 70/5mm don't know which egr spacer, explorer intake, gt40 heads,& bbk equal length shorties. any feedback definitely appreciated...

tfs-1 would give you some good results.

Thanks for the reply, specs say recalibrate maf . Did you have to do that?

ive ran the TFS-1 in a few setups, never needed to tune or recalibrate maf or any of that.. Nice lope at idle, but nothing too crazy.. idle was steady, very good even for daily driving..

Any problems with smog?I have a e cam sitting on the shelf to pop in but I keep reading/being told bad things about these cams.I really don't want to buy a new cam as money would be better spent on other things (((clutch))) but I want to do this right once before assembling this motor and reinstalling. Oh, what kind of torque curve can I expect and will it pull hard to about 6000 with springs??? thanks...

I used to have an E Cam in my old hatchback. Idled well, drive ability was good. Some people have mixed opinions on them. I will be running a tfs1 cam in my next setup though.
With my e cam, stock injectors, stock maf. Just had a surging idle problem which is fixable by doing a base idle reset. Also bumped my idle up to about 850-900 and it was good to go. And it passed smog with no problem.

I currently run an FMS F Cam. Not CARB Certified, but will pass SMOG easily in an otherwise good running car. Pulls really hard from mid RPMs to redline in comparison to the E & B cams(I've ran them both in the past) had to turn my idle up to about 850rpm to avoid idle surge. No reliability problems. If the smog tech asks it's an E Cam. Still has a nice lumpy idle. F Cam is also good for boost. Tons of people make big power with superchargers & turbos with FCams. Plus in most engines you won't have piston to valve clearance issues. You can likely sell your E cam and buy an F cam around the same price.
One of my old friends ran the F cam with cobra intake, ford aluminum heads, 70mm t/b, c&l MAF, shorty headers, off road h, & 3.55's in his full weight GT with two 12" speakers in a huge box & ran 13.1's on street tires.
While you have it apart you may want to port your lower intake. That seems to be a pretty good choke point especially for anything above the mid 5k rpm range.

My old setup with E Cam was ported/polished e7's with larger valves & bowl work, trick flow street intake, 70mm t/b & spacer, c&l maf, BBK cai, 3.73's, in an 89 coupe. Ran a best of 13.2@111 on drag radials, power really started to fall off around 5,200rpm. Some people said it was the heads, others said the cam. I figure it was a little of both.

Thanks for all your replies. Well I broke down and purchased the tfs-1 cam.It carries the split pattern with just a degrees more duration on the exhaust side compared to the e cam about the same lift with a little more on the ex side which should somewhat make up for the restrictive cats downstream. I can't wait to get r back together to see it'll do. Any of you who run this cam bothered degreeing it in or you install it straight up???

When you degree it set it up retarded 4 degrees. That will take the advance out of the cam that they put in, and help it pull a little harder up top. I have had good success with that cam installed that way, and 1.7 rockers.

I have this cam, love it. I'm going for smog on Thursday, I'll let you know how it does.
When I bought it, I would have sworn it was CA smog legal. But now I cannot find anything to confirm that, so I'm crossing my fingers it'll do well enough in the low RPMs on the dyno, as it really doesn't like to be below 1800.

People retard the timing on f303 to make it pass smog, should apply to this cam as well. Look it up

What kind of numbers are you getting from your combo? I'm looking to get around 400 to 425 @ the crank with iron gt40's pocket ported plus all the boltons listed above, the only other upgrades I have planned are underdrive pullys & freeflowing mufflers. I'd like to add roller rockers but the heads arent set up for those at this time.425 may be a tall order for this combo but anything over 400 I'd be happy with. no low gears are planned as I want this to be more of a hwy car...

400-425? How much boost are You planning on running? Not trying to flame Ya but NA Your looking at closer to 300-325 HP at the crank.

This actually didn't work for me, had to install dot-dot or I wouldn't have PTV clearance. Cam specs were spot on for valve events, and I literally just barely made the clearance...on the intake side.

Car passed smog, on the rollers. Barely, it doesn't like creeping along at 1500 rpms.
Make sure you have gears. I have 3.55s, it's just enough for this cam.

I'm willing to bet it won't even break 300 to the wheels even with those heads being ported .. Those heads are going to be the weak point in the set up I'm guessing 285 tops rwhp...

Yeah I was saying 300-325 @ the flywheel. But if He puts some drag radis on it and takes a few pounds out of it then it will be a fun street car.
Also if You are going to stay NA for a while spend a few extra bucks and go with a custom comp cam to maximize what Ya got.

285 to 325 @ the crank? wow! that takes the wind outta my sails lol! even with all the supporting mods? Are those iron heads that bad? they look alot more promising than the e7's I pulled off of it.don't want to go to wild with the cam selection as I want it to pass smog. again I appreciate all the imput. I just want enough to shut down this fool at work with a chrysler 300c heavy hemi tank n/a who thinks he a world beater lol!!!

Those gt40's are decent heads for the price, but yeah most don't see over 300rwhp. Buddy of mine had gt40's, e cam, trick flow intake and all supporting mods. Gt40's where ported. He made 270rwhp. If you want more power (320rw range) scrap the gt40 stuff.
