Intake pipes really can make power!

[SonySlave]

So I made 405hp/372tq back in February at Drift Office at 25psi with the 3065 with these mods:

2.0L 8.5:1 JE/Eagle 1G 7-bolt
HKS 264s
FP3065 w/ Dumped Tial 40 & Unported Evo 3 Manifold
Stock 1G TB & Intake Manifold
Custom 3" Intake Pipe
FIC 1600s w/ Single Re-Wired Walbro 255HP
Kinetic FMIC w/ ETS Pipes
DSMLink v2 w/ MAF-T
Apex'i N1 Turbo-back
ACT 2900 w/ Sprung 6-puck
Hallman MBC @ 25psi

Here was the dyno sheet:

When I ran that 405hp last time, I was running a tiny 3" intake pipe on the car. There was an Evo guy on EvoM running a GT3582R with the 4" S cover that was also running a 3" intake pipe like I did. After he switched to a full 4" intake pipe he gained 50hp. So we took his idea and took the little 3" intake pipe off and ran mine open turbo. I'm extremely impressed with the gain by just removing the intake!

I re-ran the car today at English Racing and the car made 444hp/398tq with the same tune at 25psi. The only mod that was different was the addition of the PTT twin-disk clutch and taking the 3" intake off!! That's a 39hp difference!!!

Here is the new dyno sheet:

My plan for the near future is to leave the boost at 25psi, leave the tune alone, and add a set of FP4R cams with Kiggly beehives, a JMF Race SMIM, and a full 4" intake into the fender. We'll see what kind of power we'll make then!

I know that I'm not making Curt Brown power on the 3065 with E85 but DAMN IT I'M HAPPY!!! :D

If I am reading this correct, these are two different dyno's?

Thats exactly what I was about to say.

[jpatter]

They are different dynos, but both dynojets and both are producing very close to the same numbers.

[Mysterio]

They are the same model of dyno just located 2 hours from each other.

Very impressive Mike, glad she is coming alive now with some power! Some big boy cams and a smim are def a must. Maybe a Magnus though...?

[Lucas English]

Have had 3 cars on it now that have both ran on the other DJ and the # are 100% the same. I can overlay both graphs and in no way can you tell they are to different dynos. The beauty of Dynojets.

I have done a lot of intake testing on our Mustang dyno so I'm not surprised at your results. We picked up 37whp on a Supra by pulling the air filter and installing a velocity stack on the end of the 4" intake tube.

On my 474whp 50 trim Laser I have a conventional 4" intake with the filter in the stock location. I built a really nice 4" aluminum low mount intake with the filter in the stock SMIC location. The result was a 15-20whp loss. Swapped the old intake back in, and boom, 473 whp. Reinstall CAI, consistant 460whp.

Thats odd. You would think that the filter being down low and pulling in cold air would give better results. I bet that on the street the results would be a bit different. I use to run a Buschur 3" cold air intake on my 1g with a GT35R. It use to make 40-41psi going to down the track. I then had a Shearer 4" aluminum cold air intake that I modified to sit flush with the front bumper. After that pipe the car held 43psi.

I took the same pipe and installed it on my brothers 35r equipped 1G. He had the same results as me. He went from making 40-41psi to 43psi.

Agreed. On the street the results would probably be different. To play it safe though, I made a 5" duct sealed to the fog light opening and routed it up to the stock filter area
