The RST is holding up great and I have maybe 10k on it. Feels just like a stocker

TSP true duals ordered!

Nice! Thats going to help a ton!

A couple details I never posted are the y-pipe is an old design, no high flow merge, & the pipe back to the muffler is only 2.75". I'll be bringing it back to the dyno after install. My guess is at least 25+rwhp. The only differences being the GZ vacuum pump & the TD's.

How's that vacuum pump? Is it a worth while bolt on?

SoFla01SSLookinstok

Well, as it's almost $1k, I don't think I would really recommend it to many. The main reasons I went with it was to get 100% of the oil mist out of the intake.

I think the main difference I noticed from it was the engine ran smoother.
Every once in awhile I would get a slight surge if I was at low rpm in gear. After installing the vacuum pump it went away. No regrets here. I'm glad I bought it.

PRC true duals installed. All in all it went pretty smooth. Except for being on my back the whole time. Big ups to this site as it's where I got all the info for the install.

Next will be to get it on the dyno for a couple pulls followed by a trip to the strip for some et's. I will post results.

Will be waiting for the results. I finally got going on my 383 getting ready to put in the car. Getting pumped up

SoFla01SSLookinstok

Thanks man! It almost feels like a different car & is pretty damn loud. I love it. Only did one pull so far & it def. feels stronger.

Awesome! Always good to see other 383 combos. I'll be keeping an eye out. Good luck man.

Man...after getting a little more seat time I can't wait to see the dyno results. That y-pipe magnaflow setup I had was choking the **** out of this thing. I have an appt. for the dyno at the beginning of next week. I'm gonna guess 501/468.

SoFla01SSLookinstok

New numbers! 492/465. From my initial run of 470/448 these were the only changes: GZ vacuum pump, TSP rumbler TDs, & a paper air filter(instead of a K&N).

Exhaust is where its at. My car felt like a stock car and would actually heat with a 3 inch cat back while idling.

I've got about the same mileage on my rst and it's awesome. Pedal is just like stock, no chatter, easy to drive and it's a much lighter assembly than a normal clutch

Wow nice improvement. Tds help a lot. Did you have a cut out on the old y?

SoFla01SSLookinstok

Seriously.

Sounds good. I'm also very happy with the rst. The pedal is just like stock.

Thanks man. I'm glad I finally did the swap. No cut out.

Ya man I'm down in south Florida for the rest of the month. If you and the other guys want to meet up let's figure something out

Wow, nice job!!

What pushrod set up are you running?

Very nice!

SoFla01SSLookinstok

Cool! I'm down man. I'll shoot you a pm.

Thanks guys.

The pushrods I have are really the only detail, of the engine, I'm not sure of. When Redline Motorsports assembled my engine that was one of only a few parts I did not supply. They measured & supplied the correct pushrods.

On another note I believe my car actually would have hit 500 rwhp. Looking at the dyno graph the pull was not even to 6k. The max tq # is 500 rpm higher than before. I would expect the hp peak rpm to rise a bit as well. My peak hp, on the base line run, was at 5900. On my new set up the 492hp is at 5750 or something. I bet either I hit or just went over 500rwhp.

Wondering if anyone noticed.
