Just to clarify, I am talking about HR street setups running on pump gas. And when referring to stock castings, I am talking about the typical ported stock castings, not some set of heads that someone spent a hundred hours reworking.

Yes, much easier to find 6rib belts than 12 ribs here.

 

hell with a supercharger...

gt76 is all you need

 

I will have to find it but a Car Combination motorsports did a 383, 236/248 114 cam, spinning the D1SC to max RPM, with gasket matched Trickflows, and a Ported intake with a 58mm, Through a 6-speed, air to water intercooler, and this was A Total Street Car. made 700RWHP an like 640RWTQ.

 

D1SC flows 1,400cfm, 40% more than an S-trim!

Ok, that makes since now Rich, I thought you was saying you haven't seen anyone make 700RWHP with Trickflow heads, But you ment with a S-trim

Also on a Side not I have always heard this and I just want to clearify since we are talking about Procharger VS Vortech

P1SC = S-Trim
D1SC = T-trim
F1 = YSI

 

So basicly, if I get afr heads I will have to get a lt4 intake. What about trickflows, will those match up to a lt1 intake

 

>AFR has LT1 heads too...

I (thought I) heard that there is a way to match up LT4 heads to LT1 intake.
If not I'm sure people here can lead you in the right direction.

 

Yes, I meant with an S-trim.

S trim = 1,000cfm
T trim = 1,200cfm
YSi = 1,600cfm

P1SC = 1,200cfm
D1SC = 1,400cfm
F1 = 1,525cfm
F1R/D1R = 2,000cfm

Thats friggin crazy talk for a street car. I am sure someone will argue with me otherwise though.

 

I don't think a SB street car could make use of 2,000cfm. A 383 running 6,500rpm would show close to 30psi with 2,000cfm. Might have a tad of detonation on pump gas! My buddy uses an F1R on his 336ci SBF and sees 26-27psi at ~7,500rpm. The motor runs on C16 (117 MON), which is not exactly practical on a street car.

The 1,200cfm range is good for a small block street car. The S-trim, at 1,000cfm is a little small, but many people have very sweet setups with them. I was very happy with mine when I ran it. I may have already mentioned another buddy who runs an S-trim on his 347SBF and runs in the mid to high nines. Of course, that car weighs only 3,300lbs.

>I only posted this to make it fair with Rich showing the ATI Procharger F1R and D1R, so I figured I should post the Z-trim too

 

Making over 800 RWHP in a street car is really about useless IMO. Athough I know friends back home that are making over 1000 RWHP in their street cars and they would argue that there is never too much power. It pretty much depends on the individual I guess. But at a certain point having to find C16 for examply may become a pain to fill your car on the way to your kids soccer game and back.

 

Thats why you emulate what GM did with their Grand Nationals, and make compression rediculously low, and make boost rediculously high, with a great bottom end.

There a guy that lives by me running 19 ( Eeek!) psi pump gas on a 9.0 to 1 LT1. It is as rediculous as it sounds. And when it makes boost, whether it is in 1st, 2nd, 3rd, or 4th gear, the tires break loose without his drag radials. Is running a 9" with 4.10 ( maybe 4.11)'s ?, M6, its a freakin beast.

Another guy is trying to get his stang going with a 10.1:1 compression for 18 PSI, on E85. In the process of working out the bugs with a double pumper, and trying to find a tuner knowledgable with E85. Should be a ****ing monster when its done.
