Hypocrisy! This site has by and large used numbers, including flow numbers, mph, ets and yes, Dyno numbers to help support claims regarding certain mods. My guess is that most members do not go to the track even when they have extensive mods---because we all know that some bad mojo can happen when you hammer on any car.

Having said that, you cannot deny that most of us post our dyno numbers, even if we don't include any graphics. This is one of the things that make the site so valuable---letting everyone know what we are doing and the results whether we use actual track numbers or dyno numbers (if for nothing else but to make a comparison before and after mods.)

And, it has happened more than a few times where members would refuse to say anything about the mods that gave them the claimed performance on the track or bench. We all accept that, even if it is somewhat contrary to our purpose.

But, when I, or anyone else, sees that someone has reported 40-50 RWHP more with a particular mod, we (I) am anxious to understand just how this, rather unusual result came about.

You all can drop kick this thread into the who- gives- a- damn bin and just accept anything and everything you read or hear about, but I will post everything about my car to the site, including any "secrets" , unlike some who don't want to disclose the specs on their "custom cam" lest someone else might learn something.

In this particular situation, I don't believe it is a matter of withholding information----but it raises the usual question as to just what one would attribute the dyno numbers given the mods.

For those of you who steadfastly claim that those numbers are not at all unusual for a hot cam, I can only say to you that I was able to get an extra 100 RWHP by installing a .....along with my baby cam.

So rather than beat this horse anymore, let's say that if you make a claim that is out of the ordinary, that you either take a wild a$$ guess as to how you got the results or in the alternative, state that you would rather not disclose how you got them. And...for the rest of you who merely respond by saying "great job" "fantastic numbers", etc. without wondering aloud how those numbers were obtained, I've got some ocean-front property in Bagdad for sale.

 

I have seen other guys with my numbers before. I didn't think it was that out of the ordinary and I feel like I backed up my "claim" with supporting mods including the fact that my car is rebuilt with pop up pistons which bumped my compression up a point or so which can definitely help. I put down 340 RWHP with full bolt ons and the hotcam which is not out of the ordinary. Then I put heads on it and got the motor rebuilt whick brought me up to 380 RWHP. Then I put a 58mm throttle body and EWP which brought me up to my current 393 RWHP. I don't see why that is so hard to believe but as soon as my roomate gets back into town I will borrow his scanner so that I can show you my dyno graph. SHEEEEEEESH!

 

Not doubting your claims. Doesn't help to say "I've seen other guys..." especially since you don't say anything about what their mods were.

Not talking about you. Just a generalization. I've been on this site since it began, and I have never seen numbers like yours with the hot cam or other similar small cam. Doesn't mean one of us is right and the other is not...just stating my experience, and.....you are just stating yours, however in your case, you have graciously provided information about your car that helps.

So with the information you have given, I am led to conclude that by using those pistons along with a 58MM TB in a 355 that the hotcam should provide such numbers.

Don't take this so seriously. The bitch is not intended for you at all. It is merely a comment on the making of out-of-the ordinary unsupported claims which leaves me either trying to figure out how the results were attained or in the alternative, dismissing the claims as bogus bench racing.

You have nicely explained how you believed you attained the results, but leave it at that instead of saying that there are lots of others who have gotten those numbers-----unless you can point out that they too had special pistons, etc.

Thank you.

 

Thank you: Now I can see from your discription how you got your numbers. Since normally just adding a hotcam with stock heads would result in around 315-320 RWHP, that since you experienced 340 RWHP with just the addition of the pistions, I now conclude that you were able to realize 20-25 RWHP just from the increase CR and pistons.

Starting from 340 and adding the heads along with the TB and EWP and gaining the additional power makes perfect sense to me.

And I am ready to conclude that the extra power came from the pistons.

Thanks again.

 

BUBBA,

I've been on this board a while, as have you (1969? ). Generally I respect your posts, but it seems in this case that you have a bug up your @ss about something. Why is it so hard to just say "Can you post the dyno sheet, those numbers are more than I typically see. Do you have other supporting mods that we should know about?"

I'll ask you this, what do YOU think he should be making with the mods he's listed? You must have an answer, or else you wouldn't be doing all this complaining. You didn't just pick this thread randomly and start ranting, it was due to the dyno #'s he posted.

Dan

 

Also if you watch my video in my sig thats on the same dyno and you can see at the end that I put down 380, it shows the dyno screen briefly. That was before the EWP and Throttle body. If I acted like I was caring too much its just because I have been defending the hotcam for a while now on this board, its a small cam that really does have some bite to it if supported correctly. I don't know when this board was started but Ive been here since 2000 and have learned alot since I was 16 haha. No hard feelings BUBBA, it takes more than that to ruin my day.

 

Saginaw? Lansing here---father born in Saginaw. Anyhoo: I guess I was just a bit flustered that no one else questioned those numbers before I shot my mouth off. Yes it does bug me a bit when others do not question out-of -the ordinary claims and just go along like nothing seems awry.

In my opinion, it does nothing to enhance our purpose if claimants do not provide sufficient data or that others do not ask for that data.

I didn't believe that I should ask for proof, since I was not doubting the claims, but rather questioning the results given that there was little data to conclude those results.

And as for my guess as to what his numbers should be----I haven't a clue, since I don't know what one should expect from the mods reported.

Just as a WAG, I'd expect that a hot cammed lt1 w/ middies, stock CR and pistons with a mail-order tune would probably get you 315-320 +- rwhp on a dyno jet. Add some decent heads, add another 25-30 RWHP. Throw in a 58 TB and EWP and I would guess around 360-365 RWHP.

So 393-365=28 RWHP gained, assumedly from the pistons---which makes me want to run out and get some.

So now that I have provided my guess at what the results would normally be, how about you or someone else helping out by offering an opinion---I'm just trying to contribute to the purpose of the site----I'm not trying to be an A$$ about it. And if everyone else believes that I'm just being difficult, rather than merely trying to aid the cause, I can't do much about that. JMHO

 

Well I never care really about the HP output of a cars mods in relation to the track. There can be many very different varialble when out on the track. However being an owner of a HOT CAM car that put down 324 hp to the wheels with STOCK heads and a full exhaust including cats on a mail order tune in an AUTOMATIC, I can see how these numbers can exists. I have a friend that I will see if he still has his dyno sheet from his old 97 ram air TA that had locally ported heads and a HOT CAM thaty dyno'd 400 HP to the wheels on a stock bottom end with a M6. I called BS but his car was a freak. Trapped strong MPH that would definately indicate a 400RWHP dyno time. Back to me. I installed a set of GTP heads along with Vig3600 stall and had the car on a dyno for 3 pulls with the same old tune. It was all over the place but the third pull was 360 rwhp that I am still not sold on because the first pull was 278 rwhp and the second was a smooth 345 rwhp. Now I could claim to have the 360 rwhp but the dyno I was on I was not convinced it was correct. So I still have my cam only HP numbers that I go by until I get back on a dyno. No 2 cars are identical and can really show incredible gains as well as below expectations with a single cam. My car bone stock ran a 13.99 @ 99 mph and was considered a "faster" than normal bone stok 1994 Z24 with an auomatic around my area. Once again I will never claim bs unless it is something waaaaaay off base with the norm. But I am too curious of what other mods are done to get a strong #. I will neve doubt anything anymore.........

 

Good reply BUBBA. Are you in Lansing? Under your avatar it says Portland?

The Hotcam with stock heads, M6, mids or LT's and 1.6RR's is a 325-335 rwhp car normally. The highest I've seen with stock heads and hotcam with a M6 is 355 rwhp/ 350 rwtq by GREGG 97Z. He has pretty much ALL the supporting mods though. He has the dyno chart on his site and has hit 12.019@115+ in the 1/4. http://www.gowman.cz28.com/

The Hotcam has surprised a lot of people.

Dan

 

Brent94Z(one of the owners, or something) put down 399 with the hotcam and heads.

 

Wow, I was blown away when I read the #'s you hit, I wasnt aware they were possible with the hotcam and headwork. I'm still running the hotcam and working on porting my stock heads now and upgrading the valve train (crane 10308-1 springs, raceflo 2.0/1.56 valves) and bumping the CR to close to 11:1. Im expecting my heads to flow around 250-255 when Im done. I'd be very happy with #'s in the 370-380 range, but we'll see.

Two questions Quicksilver, what size injectors are you using and who did your programming?

 

42# Racetronix injectors and my tune is a dynotune done with LT1 edit from a local guy here in Austin, Tx.

 

Stero: No, I'm in Portland, OR now. One of those things where you wind up some place you never ever even thought of-----just the way things go.

Anyway, I see from several responses now that the Hot Cam can produce some pretty impressive numbers. When you say that people get into the 330 range without heads, I can see how that with some nice heads you would get some great numbers. It still just seems odd, especially when you see cams like the 306 etc ony gettin those kinds of numbers.

Seeing a relatively small cam like the hot cam getting 393 RWHP (which equates roughtly to over 460 crank still makes me shake my head, since with numbers like that and a good hook, one would expect low 11s at around 120 MPH.

Anyway, those who have gotten impressive numbers from the hot cam, with or without heads are more than welcome to post your dyno sheets----I'm rethinking some stuff on the best cam for my ride.

Thanks. And nice to meet a fellow Michigander, Stero.
