Skinny I make 442rwtq to the wheels That's close enough for a 500 crank. Exactly about a 355ci making that much power, there just isnt enough there.

CaliBranden

I think Jerry's car is a race car now Id say, he already did some Mods to his rear body.
Vincent thinks he can take out bigger motors so let's see if it is really possible.

Dyno Don

Well...I guess you stroker guys have a little work to do to your body to catch up to him. You have the big inches....go play with the big guns. You can't have it both ways.

CaliBranden

Ok what ever you say. But you laughed when Ivan responded and we don't even know, He might have a low 12second car. So this 08 is going to be a big race year now that everybody is going to have there cars built and some rebuilt. Could be a fun year.

InsaneIROC

Oh really

We have a lot more to do then body work. First we have to spend what 5k plus for an aluminum block. That's not a street car that's a race car and you know that. I really don't understand why you keep building 355ci. How many motor swaps has Vincent done already? Not just the block but cams heads and so on. How much power you going to get from a cam swap?

skinny z

Back in my college days (late 70's) my engines professor said to me, " If you want to go fast on the street, put the biggest engine you can between the fenders." That's after I had suggested I'd like to build a stroker 350 instead of the 400 I had on the shop bench. I guess the same holds true today.

skinny z

By the way, and this seems to be the forum to ask the question considering all the heavy duty TPI engines out there, does anyone ( I know Vincent did) use the factory twin element air filter housing? It seems to me that you guys are making WELL over 400 hp and I'd like to adapt it to my application. I know there are secrets that some of you like to keep to yourselves, however if anyone is willing to share their expertise, I promise not to drive down to So Cal ( my old man is in San Diego ) and beat you in a race.

CaliBranden

Are you talking about the Ram Air?

Kevin91Z

You mean the black air snorkel that goes over the radiator to the filters? The stock piece? Yes all the Camaro guys are using that. Jerry is using the SLP one, though.

skinny z

SLP makes one for a 3rd gen? I'll have to look that one up.
Thanks. I'd like to keep to keep the stock hood. I kind of the like the sleeper look. Stock appearing on the outside....

VincentZ28

See what you don't know Branden is that I've raced aganist 383's and 406's on the street for money and beat them in a heads up race. So I know what I'm talking about.

Now find a way to get some stripes under you belt and breath before you step up to the big dogs. I tell you what, Beat Julie first. That might be a big accomplishment for you.

CaliBranden

Vincent I dont need any belts. What's Julie going to do? You come in here Naming me you must have beaten some bad drivers or weak 406 because you have not even proved any power over Ken. You know your not going to gain much with a 355. A kid already come in here and said How in the hell you going to make 500hp at the crank with a 355? And my only question was how much power you going to make with a cam swap, that was all.


Don said we cant race 355ci motor and be number 1 N/A So whats the point proven you anything? You know dam well the bigger liters here are going to win. So I think this year being a good year to race I think we should be in our own class, Like Don is saying and keep to our own race class. There is enough people here with bigger cubes that we can race an be fair.And have our own N/A Fastest So Ca. It's not always going to be 350-355ci Why should you guys always be number one? So when we get our own fastest N/A So Ca 3rdgen it's going to mean something. Because proven you anything is not going anywhere, Why because you said you already beat bigger liters. And hell like Im so interested in racing my car. Like I could even beat InsaneIroc or Ivan, Alex, or 90-irocdx3. They all have me in liters plus bigger cams better heads more gear some 6 speeds And making more power than most the 355 already built.

So there that is that and that is fair. This probably be my last year for racing my car anyways. Just for fun nothing to prove, just bettering my times becasue I raced at irwindale with a bad o2 sensor. And Im wondering how better the car would run.

RWB____s

Larger cubic inch engines are only as good as the guy who did the engine work, parts combination, the person tuning it, and how the car is prepared its running in.
In the late 1970's/early80's I beat many 454/468's at the old OCIR dragstrip with a standard bore 396.
So it is totally possible that a 355 can take down a larger ci smallblock.
As for the 500hp mark, The engine in my car was (engine) dynoed at over 500hp/460Tq N/A with a carb.
For those who thought I was running a solid roller motor when my car was dynoed a few years back at the group dyno, the cam that was used that night was only .520 net lift in a 10-1 N/A engine. The overall numbers were alittle low for it 415/390 @ the wheels(I messed with the combo and a very bad tune on my part plus I did no tuning on the car during any of the runs) :-).
Vince and some others where running .560+ rollers, did alot of tuning for power, and had the magical fuel injection. Go figure :/

90-irocdx3

tommorow is dyno day for me, so hopefully i can come up with some good numbers..

Imadude_134

I cant imagine what a run in all of your cars feels like... I just (finally) got an L98, and I am amazed at how different it feels from the LO3...

So my goal for 08 is not to beat anyone here (cuz I KNOW i WONT), my goal is to beat my previous time (in the LO3)... I think that I'm there already, tho... so I can tke 08 off

Good luck to all you with your builds

TA

Peak power is not determined by engine size, but as has been discussed, is dependent on the combo's RPM potential and tuning, and what it is designed to accomplish. However, at any given peak power figure, a larger engine usually makes the peak at a lower RPM and has more bottom end torque and better "street" manners, but that, too, is a tendency and NOT a rule.


TA

CaliBranden

I truely understand what all of you have said. TA is right most the power is down low but that's not only the case. My car was only brought out at 5,400-5,600 rpm but I still would have made more hp up to 6,200- 6,400. So all together the car has a lot of power. But you cant just say the average tpi 355ci is not going to walk all over me. If it's fast it's going to be a side by side race. I think it's just best to focus on where we need to be. And we can have a 2nd top 3rdgen and it doesnt even have to run as fast as the 355ci.

skinny z

...and this is all smog legal?

CaliBranden

Don't ask those questions. haha yes and no.

skinny z

Yeah...we have smog laws here too!

CaliBranden

Most everyone here passes smog.

brandotron

I'm in the same boat! I just moved up from my 3.1 at the end of 2007! So much cooler having an engine people actually make parts for!

2008 will be the year I rip my car apart and spend way too much money...

I don't see any 383's at the top of this list nor in front of me. http://www.sc3g.org/phpBB2/viewtopic.php?t=34

CaliBranden

Vincent that list is pretty old. And there is only three 383ci, however you have not met us at track yet. Ben has not been around for awhile and last I knew his car was not all running that great and he pulled of those times, thats pretty good. Rual I dont know who he is, and Dwayne car is probably faster than his last Et's.

Vincent you may have the Et at the moment but why cant you match our rwhp? Gene has told you to build something better, I mean hell I would like to see someone step up out of the 355. With the parts you have you could build an awesome motor. By the time I upgrade my car to better parts I wont be around. I do know that I will make more power when I do.

TA

With all his tongue-wagging, Vincent must be doing some of his own "secret updates" on his engine, . How are we supposed to catch up if you keep moving? You're not cheating fair!!
