Lindsey Racing Intake - Review

[ae1969]

I picked one of these up for my B-Day for my 944 Turbo.

I must say I was quite impressed with the workmanship on this piece. I own a few LR products and this one is definitely top notch.

One of the main reasons I bought this intake was to equalize the flow over the 4 runners. THe 944 turbo under boost applications historically will lean out #4 first.

I have been testing some of the extremes of my set up..........and at the same time have roasted 2 head gaskets over the summer in the name of science.


My current setup

- Vitesse Stage 2 (t04e), 240 CFM head, 55 lb injectors, Smt6, LR fuel rail, SFR 3" testpipe/Cat back, AVC-R etc.... etc. etc..

1st Tests

91 Octane at over +21 psi - Car runs very strong. EGT's would occasionally peak excessively high at 1500+F on #4 runner and she finally blew the gasket. THe AFR was set at this point at 12.0 at 3.5Krpm to redline...............

2nd Tests

91 and 94 Octane at over +22 psi - Car runs very strong. EGTs still would rise on #4. ~1450F. The AFR was set to run 10.5 at 3.5Krpm to redline. She finally blew.

The first 2 headgaskets showed serious detonation on #4. The ring was pounded in every segment. 1,2 and 3 were in very good shape with the occasional dent.

****

Install Lindsey racing INtake for the third test.

3rd Test (only the first week and hopefully the results stay true)

94 Octane at over +21 psi and setup like test #2.

- idle smoothed out (but that was probably an intake leak I was chasing)
- AFR that was previously at 10.5 to redline...... was now going of the scale RICH on #4. The 4th runner was now getting less flow (equalized).

The intake definitely addresses one of the short comings of the stock intake.

I will finally re-tune and lean it out to optimize power and get her on the dyno.

Thanks for the write-up. Good to know the LR intake is a quality built product, and can help even a car that is virtually stock...like mine.

Keep us updated.

Wow sweet test you have run. I bet that is one killer 951 at 21 and 22 psi thats crazy boooooost. I had no idea you had a setup like that. ANyway keep up the good work and keep us posted.

P.S HAv you thought about upgrading your head gasket? I know Guru Racing makes a really nice one that wont burn up in high booost

I ran an MLS gasket a couple of years ago. She eventually let go. Unless the head and the block are skimmed I would not ever do it again. It needs 2 perfect surfaces to run.

The stock ones are cheaper to replace in the long run.

You're going to have to take me for a ride again with these new settings and the "Lindsey Racin" intake. It's almost time to strap that beast down to a dyno and see what she's putting to the ground.

You guys know that's actually Alex's car in his avatar... and that's not tire smoke
