and btw do you have any vids if dyno?

 

Nice comparison! Its nice to see some actual solid info on our cams. FWIW my car made 370whp and 292tq on the dynojet at MAP in MN with basically the same setup except on a 2.6" pulley and 3" exhaust, although I'm losing 2-3 lbs of boost after 6k. Have to fix my boost leak tester and pressure test it to 25 lbs and then maybe swap bypass actuators.

 

No vids of dyno but I want to get an ATI dampner and neutral balance shafts and see how much it makes at 8500 rpms. maybe 380 is possible!

The peak torque is at 75-80 mph but stays pretty flat all the way to 7500 rpms.

Infra: my boost went down 3.5 psi the whole rpm range with the new cams. and yes I like them, they make more torque and hp throughout the powerband.

 

i would love to see a tvs lsj car with these hp numbers & setup run a 400whp turbo lsj just to see how much of a difference you can tell the power range in both cars etc

anyways i love your setup man and congrats on your new numbers, hopely you can squeeze a bit more outta her

 

380 is possible on stock cams and has been done if you cant break 390 to over 400 you need a new tuner

 

Best I can do for you is I ran NWSS's car before he parted it out and I bought some "certain" parts It was S252et on 22 lbs and 91 gutted to 2700lbs tuned by me. He had a 300 lb passenger and I had a 150lb passenger and from back to back 40 and 55 rolls I got a solid few car lengths, we switched passengers and my car got stupid hot (3 pulls to 130+ in 5 minutes will do that lol) and we were then dead even. I has videos.

 

INFRA thats badass man, i wants vids lol

 

well my new setup gained 95 hp over my m62 setup so im thrilled about that. And as for a new tuner I think Tim did fine. I mean im happy with the car so thats whats important. Im sure if I rev it out to 8500 ill make the numbers everyone is looking for. but they are just numbers. And I would think a LSJ T would pull on me just because of the superior torque they make? but Infra's story says otherwise. And thanks Johnathon I love they new setup. she is a terror on the street now. I get idle surge though which is annoying sometimes. and MRB who broke 380? I dont think ill ever hit 400

 

area47 hit 375 or 380 on stock cams

im not busting on you but the tvs is a 100hp bolt on over stock. good cams should push it over 400

 

I know you arent busting on me, we have had a few good phone conversations about my build. And my previous setup is about 100 below. however that is with cams. So im hoping this coming winter ill be able to get the supporting mods to really put this blower/cam combo to good use!

 

I don't think you need to rev it any further than 8k man.

By 8k the S2 cams will prob start to drop off.

 

Hmm well Tim said he wanted to rev it out to 8500 when I was there but I guess we will eventually see where it stops making power. When do yours start to drop off staged? I know you havent dynoed but can you feel where they peak?

 

Mine pulls strong all the way to 7.5k, but there is no way to really know yet....

I'm going to do a few Gtech pro runs to pull a power graph. I have mine calibrated nicely.

I actually have some Gtech pro runs before cams & with/without race gas. I just need the correct cable to upload them to my computer.

Before cams my power peaked around 6800 rpm. I'm willing to bet my power peak is around 7300-7400 rpm now.

 

My peak hp was made at 7600 and then it started to fall hard, but mine is a worthless comparison because at 6k my boost started to drop and then at 7400 it tanked pretty bad, so the airflow was just lacking. Really hoping to track down my issues this week, just need to find time. Always helping everyone else out.

 

I wish we had someone with a balanced engine that had these cams so we could see where they max out at... Oh well before us no one had any factual data on these cams. just forum speculation....

Although I would think the stage 2 cams would pull at least a few hundred rpms higher than stage 1 but who knows at this point.

 

when I posted it wasn't speculation and you don't need a balanced rotating assembly to spin to 8000

 

Min and max boost was higher by 3 psi on run 2. Anything else change with the car or do the cams add higher boost to a fixed pulley supercharger?

Nevermind I just looked again and the 2nd run was the lower HP run with higher boost levels seen. Cams help breathing efficiency so they typically lower boost (restriction) levels.

 

Yep, I dropped about .5 psi after my cam install.

 

I seemed to get the opposite effect. My boost raised slightly if anything. I thought it was odd.

 

Cant hurt to have one before though. And where do you think they will peak at MR B?

 

And yes terminator. I dont have a scanner so I took the best pictures I could. But the average boost dropped by 3 psi ish

 

I thought 8300 was the ECMs limit?

 

There is an in gear multiplier. You can technically set it to 16,384 lol

 

Ah did not know that. Thanks for the info.

 

on a 2.8 I was seeing 20+ at 6500

im guessing around 7500 comp cams told me that 7200-7400

the custom cams I had ground are supposed to be from 3000 to 8200

on a side note are47 made 342hp on a 3.1tvs pulley and gmr cams 93 and meth
