I agree it wasn't perfect, but still very impressive.
The boost difference pre/post laminova caught my interest the most. Magically fitting a massive bar/plate core I to an IM may result in higher flow but at the cost of cooling.

its not a turn of events they are good cams but not what I want

streetable is different for everyone

the cams are worth it the car drives like its stock you get a gain everywhere in power plug and play and I think the stg1 or 2 cams would work well on a road course you can have all that for a fair price I liked the stg2 cams I just want more mid to top

I don't need to post proof it has already been done and there is not other people on this forum (just 1 person) saying the cams aren't worth it

I agree with this from my experience with my S1 cams.

You can feel the additional power throughout the rpm band for sure. Very nice upper rpm power, and no "noticeable" low end power loss. My car idles great (with a mild lope to the exhaust), and I still get great gas mileage.

All my parameters check out great to, no knock anywhere, fuel trims in check, etc.

I'm going to dyno my car either this month or in the fall. All depends where I am with everything else I have going on in my life.... I plan on testing the difference between 93 octane mode & high octane mode.

Since my last dyno was done a few years back, and at a different dyno (no longer in business), I can not use it as an accurate comparrison between stock cams vs. S1 cams, but it will be nice just to see where I'm at now.

this, right here. pay attention to it when others are suggesting mods. i could DD a ls car with a 248/252 .630 cam and be fine

that is why the zzp cams are good for most on here easy to drive

I use to have a 1967 Plymouth belevedere 4800 stall 4:30 on a spool solid roller fun car old school mopar is where its at

love those cars. i daily drive a 3.1 stroker 280z with a rowdy ass cam in it and side drafts.

Back from the grave...

In case anyone missed the dyno, here you go. This is w/ATI Damper and the 2.7" ring installed.

Best time so far at the track is 13.2 @ 111mph on street tires, 2.2 60ft.

Slicks are sitting in my garage for next season.

TVS on deck and waiting to be installed.

Let's see how far I can push this stock block now. I have an itch for more displacement if it ever was to fail.

Nice times. Back on stock head and stock cams I went 13.6 @109.7 on a 2.7 on street tires with a 2.25 60' for comparison. I'm tempted to run my stock blower car at the track once this year. Thinking I'll take my turbo one to the nice track that is farther away, and then when a big group of us go to the closer track I'll drive the stock blower one with slicks, with Euth head and S2 cams, just no ATI.

Nice! You gotta run it just for some giggles.

I really want to! I think I will. Its a fun car, and it hurts peoples feelings on the stock blower and stock catback lol, its so quiet. Strap the slicks to it and go 12's and you do the same.

I wish I had dat quiet, i'd love to hear only whine without the BAAAAAAAAAAAH

Its LOUUUUUUD lol. I haven't had a stock catback for over 5 years, and never with a 2.7". Such scream, so noise!

100% agree. i am still currently running stock catback with 2.7, the sc screams and the exhuast is quiet.

I'm jealous. Put that car on some slicks and see what it can do before you swap the supercharger. I wish we had E85 out here.

Was this on 91 Octane? I assume that's fully bolted with cooling mods. Most likely with methanol injection? I'm frustrated with my times that I have been hitting. I'm finally going with a set of slicks if I can afford to purchase a set this year.

What benefits are there to having the ATI pulley? I'm going to research but what does it help with?

I would love to hit a 12.8 on my M62 and before I have people saying that I won't hit that time, I disagree. I have will have the power level for what it takes and there's nothing a little bit of race fuel can't fix. Hatrickstu went 12.75 with MUCH less work done than me, he was using race fuel though.

My tuner went 13.0 @ 111 MPH on Drag radials (2.095 60')with a fully bolted car and methanol injection. Kind of where I'm basing mine from.

Sorry for the rant. You both have some of the most respectable cars on this site. There aren't many cars I look up to on this site but these are two of the few I do like.

That was on E85 and a 2.7" pulley, header, 2.5" dp, and a catback. Stock cooling. My first crack at tuning it on E85 about 4 years ago. There was power left in the car, I just didn't know it at the time. I also wasn't too great at driving at the track. If I run my M62 car this year I plan to get into the 12's since I can throw my slicks on it. It has the stock catback and a catted 2.5" dp, but ported head and S2 cams. The track we run at is inconsistent though, but it will still be fun either way.

The ATI effectively drops a pulley size due to its larger diameter on SC cars, but more importantly it dampens and "balances" the rotating assembly. More so does a good job at eliminating vibrations that like to rattle things apart in the high rpm's. I have never ran one yet, but I have one on my 2.1 in my red car.

it dose not take as much hp as people think to put these cars in the 12s on a m62 its more driver then anything

InfraRedline

Driver and traction. I've had days at my track back on the 2.9 TVS with ported head where I couldn't break below a 13.0. No matter what I couldn't cut better than a 2.2 60 and roast the tires off through 2nd even on the slicks. My track also rarely has any prep, got lucky the time I ran my 12.2 since it happened to be the weekend after their drag finals.

That's why I think I'll run at proving grounds at BIR this year on the turbo setup. That is a great track. 5-6 hours away though.

The only one I really ever have to practice is 1-2 because I NEVER do it on the street

For some reason (and I never had this problem with any other car) I have trouble with 2-3. Seems like half the time I hit a wall between 1-3. And of course it usually happens when racing lol

1-2 is what kills me as well. I watched Stu race back in the day and his 1-2 was incredible.
