hotter engines are more efficient. Cooler engines often make more power. Especially if the rings are worn.

Well yeah, that is obvious. You don't want to be running at 250*

I recommend eibach springs, and koni struts and shocks. Install a true LSD in the trans. Run some fat tires. You should be able to pull off a 1.9 60 ft on street tires at the track.

[iloveshelbys]

got any pics of this engine?

[Ondonti]

I have slicks for traction.
This is a race car.

I have a cheap car for driving called a dodge spirit.
Thank you josh and electric for pointing out things that are beyond speculation.

(im kinda curious when ill hit the max sustainable limit on my 92 duster fuel system if i S/C my 24v...) also, on my 12v and even on my 24v, on a cold start redline rev, ill push past 100psi (brand new sunpro gauge) on warmup, less than 20 psi at idle hey, thats also the same color as my duster! (2dr 5sp brent?) also what are you going to do about traction? im thinking i might have some traction issues when i S/C the 24v i swapped in

Read page 25 where I posted pictures.
Besides what Posted there, I have a 255high pressure walbro and in installed a 5/16" return line so I could achieve lower base fuel pressure with the 255 pump. Stock pump and 1/4" line I could only get down to 26 psi. I think with the 5/16" line it is down to 20 psi using the 255 walbro. My fuel pressure gauge seems to be damaged though and reading 20 psi too high. No way my car could run with 40 psi fuel pressure on 47# Injectors. That would be 200% more fuel then stock to idle.
Rising Rate Regulator tuned by using my wideband and EGT datalogging with datalogged boost too.

so you dont know what your fuel pressure is? thats kinda important for tuning. i may have an extra gauge i would be willing to part w/ for cheap if your interested.

It should be at 20 psi right now. The piece of crap came with a plastic cover that got clouded by gasoline so I had to break off the cover. Then the needle was free to get messed with. Seems it got pushed or hit by something over the last few months.
I need a fuel gauge that can fit into my regulator. I think its 1/4 NPT

[Ntrain2k]

I used this one with my reg. Screwed right into the port:

[Ondonti]

does it have a plastic face?

the face on mine corroded when gasoline touched it.

A hotter engine lasts longer for ring life. For a street car, 180 is the coldest you should go

Congrats on getting the oil issue worked out, can't wait to see fast this baby is. Any dyno plans?

[Ondonti]

Well Im pretty sure Im gonna hit the dyno. I missed the whole season of racing so I didnt spend anything on that.

it is the best way to tune...especially if you ever get that ms up and running.

[Ondonti]

Well, I just went for the first real break in.

Let me say I screwed up bad. Something started leaking oil and dumped my oil suppy.

Im sure at least my bearings are toast, maybe the crank too.

BTW, 3rd gear torque steer from wheelspin on only 5 psi boost.
I feel sick now blah.
