I have used Nitto DR's and BFG DR's. The BFG's are great. They launch nice and smooth with me getting easy 1.8 60fts on a poorly prepped track. They have just enough slip to not shock the driveline to bad. My nitto's did not have nearly as much grip and they also had the tendency to cause wheel...

Has anyone monitored the timing? Sorry if I missed this, but has anyone actually used the MAFT-pro to see how many degrees of timing our cars are running at high rpm's? I know it will vary, but I was just wondering.

"Whoooaaaa..............the only MAJOR things I didn't have installed was the catback and the backseats." Yeah, thats why I'm so surprised on how light it is. You lost a good chunk of weight with those FD wheels, at least 6-7 pounds per wheel.

Your car weighed 3240 with just a catback, and backseat removed?? Lets try to make some sense out of this. An 87-88 hardtop according to C&D magazine weighs 3588 pounds with a full tank of gas(108 pounds). Empty the gas=3480, minus the back seat(35lbs)=3445, minus the catback(30lbs)=3415...

You should be fine without the AFPR. I have one on my car, but my fuel pressure is kept on the stock fuel pressure setting, so I don't really use it. With 550cc injectors, your going to be running rich no matter what. You can try and adjust the fuel pressure to lean it out, but thats going to...

I ran a 12.7 at 117mph with 19psi with a horrible launch. That was with my SP61GT. I usually boost over 20psi at the track so I can't remember many more sub-20psi runs.

It doesn't cost a lot to have a stock intenaled 7M rebuilt. Probably less than most used 1JZ engines. Then you have a new engine and no hassles with the install. I have about 35k miles on my 7M since it was rebuilt by the previous owner. The only real flaw in the 7M is the factory torque specs...

Sounds like theres a lot of bad mechanics in the Dominican Republic. A 14 second 7M powered car is nothing. Just retorqing the 7M head will give you fool proof way to a make 210-260rwhp (which is about all you need to run a 14 second 1/4 mile). You can tell your boys down in the Dominican that...

No tuning and low boost will probably only give you about 375rwhp with the SP61GT.

Yeah its definantly a ricer mod..It makes me wonder why people spend $150 for a little pipe or $45 for buttons. I spent 5 dollars on a foot long mild steel pipe, and then covered it with reflective thermo wrap so it will avoid heat soak and still cover up the ugly pipe.

I think either gasket will work fine. I have the Cometic 2mm headgasket. The prep work on my head was perfect, but the block surface was not nearly as clean and it sealed. I recently ran 30+ psi accidentally on my SP59GT and lifted my head. Got the gurgling sound and started losing coolant...

I can clearly feel the difference between 93 octane and 110 octane when I'm running 18psi. Thats whats going to be nice about the MAFT-PRO; We will finally be able to monitor timing and see at what point our ECU's pull timing when detecting knock.

I went with the horsepowerfreaks bronze clutch using the ACT pressure pressure plate for fairly light pedal effort. Its capable and proven to hold 600rwhp.

Yeah, I beleive Bob Norwood dynoed at 934rwhp on his 7M powered MK3. Its fun to talk about making big horsepower. But in reality, anything over 450rwhp is hard to put to use at low speeds, especially in first and second gear.

Just as a little follow up.. I removed my wastegate last night. The wastegate looked to be funtioning fine with no sticking or too high spring pressure. I was stumped until I noticed a little sctach on my vacuum line thats connects to the side port of the wastegate. Well, it turned out that the...

Thanks. So I guess what I'm asking is, do I have it hooked up properly to check it the wastegate is funtioning? I have the vacuum line running straight from the turbo compressor to the side(bottom) port of the wastegate.

Yeah, without the AVCR solenoid connected, I have it hooked up to the bottom(side port) of the wastegate. I just left the top port open for now. With the AVCR hooked up: I had the NC port hooked up to the the T with one line going to the compressor housing and the other line going to the...

I should make it clear that its not opening at 20psi, its opening way past 20psi, and I'm having to lift off the gas before blowing my motor.

Now that I have figured out how to hook my AVCR boost controller to my HKS external wastegate(thanks to Chevyeater and a couple others on Supraforums), I still can't figure out why I'm overboosting. I decided to eliminate my boost controller and just route the vacuum line from the turbo...

I would start out with an open dump. Then when all the noise gets old, you can always have it rerouted.
