Beautiful build and a very nice car indeed... One thing i'd like to point out though, but before i do

I am only offering CONSTRUCTIVE criticizm The way the pipes come out of your FMIC has been shown to be one of the least efficient ways you cna build your end tanks (squared off with the outlets 90* from the core's flow and tank end, because it's not a smooth transition in or out of the core.. I think there's something to gain if you were to bring the outlets straight out each end in the direction of flow, or built the front part of the end tanks with a "rounded" shape to direct the air to the outlets and throught the core from the inlet...again, not sayin anything bad, just offering some advice that i've come across many times in my years of building cars, turbo kits and fabbing end tanks for cores as well..sometimes it can't be helped, but if you have room, it might make some gains!!

Backdoor entry FMIC's have been shown to provide good airflow distribution across the frontal surface area of the core with tight packaging. Sure 90 degree turns don't flow the best but the turbulators in the FMIC also don't aide flow. The tapered entry and exit end cores do flow well but require the kind of room that really isn't available in most cars. Its a good compromise and seeing as John is making 1000hp I'd say the compromise is working quite well.

danl is actually right in the sense of cooling effects on the backdoor style end tanks, because they disperse the air across the core more evenly. Now a properly designed end tank on any intercooler will make sure this effect is achieved by adding vanes to keep the air from just going "straight through" and instead routing it to utilize the entire core. Lots of good info on end tank design and theory here... Intercooler end tank design

Went back to the track this time, good news is I brought fuel, bad news is I forgot the laptop so could not turn it up.

First pass off the trailer got to aggressive with the launch spun hard, then when the car went into 4th and across the 1/8 mile car spun badly and went toward the wall so I lifted corrected and got back in it but it had fell so far out of boost it barely made it by the time I crossed the line.

1.7 60''
[email protected] 1/8 mile
[email protected] 1/4 mile

Had I just breathed and not lifted first pass off the trailer tonight would have been a solid 9. Best I can tell boost was in the mid to high 30s.

Unfortunately track was packed so I watched 70 or so street cars tear up the surface and put water all over the place before I could try again. Left with a little less boost but spun again, and then the show started. Car ran hard left and touched the center line, I lifted and shifted then it ran hard right, I lifted and shifted and it ran hard left again, once in 4th I was just sawing the steering wheel back and forth the rest of the run. Track guys wanted to tech the cars because it was all over the place, after they did I decided it better to bring it home and change some things and wait for a better prepped track before I hurt myself the car or someone else. With all the lifting and crap car went...

1.61 60'

[email protected] 1/4 mile

Gonna put in some active toe eliminators, replace a couple bushings that are not urethane in the rear and perhaps a new set of slicks and lower tire pressure. May try some Hoosiers for more contact patch as well.

Overall I am happy, car didn't break and I can try again with a few changes later and have a lot more boost to throw at it.

 

[streetdsmpwr]

What tires were you using on those runs?

 

[JohnTSI]

24.5 M&H Racemaster slicks

 

[954TalonTsi]

Crazy times for all the lifting you did. I guess even 24.5 racemasters and four wheel drive cant hold a beast like yours!! Hope you get a better prepped/less crowded track next time. Amazing build

 

[GDNF2ET]

How much of a difference did the Magnus intake make ?

 

[JohnTSI]

You can see the difference in the intake manifold thread, my car is the one he posted dyno graphs for. It picked up as much as 80 in the middle vs the manifold I had on it before, magnus drag manifold. I can't tell you about what it did vs anything else just what was on the car before.

 

[JohnTSI]

Went back today, only made one pass since it was WAY too hot (intake temps 115* on the starting line). boost 38-40psi but I am a idiot and granny shifted 2-3 and 3-4 and it fell to 18psi on the shifts and if you ever drive a 42r car you know that's a bad day.

1.52 60'

Boost recovery killed the top of the track but all in all I am happy its getting faster every pass and still not turned all the way up yet.

 

[kp116]

125mph in the 1/8! That thing is flying! Any videos?

 

[JohnTSI]

Will bring the gopro next time.

 

[richard33]

nice times! So what are your goals with this car and all that power once you get everything dialed in?

 

[9!'clipseDOHC]

You're getting that 60' down too! Congrats on the 9 second pass!

 

[JohnTSI]

Goals are just to go fast.

 

[DSMer541]

Amazing.. I know you said before you have considered an auto tranny for the 1/4 , have you not yet tried an auto yet?? Jeff Bush's ETS 1g car is making a little less power but still over 1000 and is in the 8's trapping over 165.. I would be curiouse to see what your car would do with an auto setup, I'm sure 8's would be easy... But still an Amazing car man! Love it!!

Here's a thread to help get you caught up on John's automatic car Full weight car and its 7 years ago..It would go on to run in the nines...

[JohnTSI]

We have enough autos at the shop. This one is gonna earn its ET the hard way. Its more just learning to handle the car at this power level before I add more power, its not like driving a 35r car.

 

[DSMer541]

well then thats just bad-ass , still using factory 1g gears?

 

[JohnTSI]

Yes, stock 1g gears

 

[JohnTSI]

Well went back to the track again today, and after waiting 6 hours to get the tree working and watching 4 hours of pinks style arm drop racing got to make 1 pass. Fuel sloshing issue killed me again as pickup sucked air and shut the car down at the top of 2nd and 3rd also lifted when it got loose for a second on the big end. Eighth mile MPH showed promise though I botched the launch.

1.700 60'
4.658 330'
6.655@131.7!

A civic hit the wall after that and we didn't get any more passes. One clean pass and this thing will really move!

Fuel cell install this week!

 

[olmytsi]

That's moving!!!

 

[JohnTSI]

Added the cell last week.

Then went back this Friday night with the cell, blew off a IC pipe between the 1/8 mile and 330' did run a personal best 330 in the car of a 4.1, previous best 4.37, hit the brakes and went a 6.6@90mph, this all on a sub par 1.61 60'. But I got the information I needed, car is flat out of fuel at this power level on the track IDC went into the 120s and AF high 13s.

Pulled the manifold today and will have it on its way back to Marco on Monday for a second rail to be added. FIC sent a set of HiZ 1000s to run staged with these 2150s, so I should have enough fuel to run much more power on the next outing.

That a lot of fuel!!! Keep pushing it, you've got lots of people following your progress and wishing you luck!

 

[JohnTSI]

Thanks for the kind words. Car is progressing constantly and I know it makes enough power to run what I want it to. Its just working at all out and getting it there. Right now I am happy it can run a high 9 on a crap pass.

 

[antilag_200]

That is awesome and very inspirational.

Good luck in your goals

 

[Jstue]

Wow! thats really fast. very nice and clean shop.
