Turbo 408 finally close to done!
My 408 single turbo with RPM trans with 2 step and eboost controller and Yank stall finally going back together next week.
I had alot of issues with this project with my job transfer the car was in Atlanta I am living in Carmel, IN so I had ED Potter from late model speed go to Atlanta to get the car and start from scratch to put the car back together. The 408 is at his shop and at 8.5 comp chasis dynoed at engine shop 497hp-492tq with forged parts and Trick flow heads. The single turbo is a 76 mm custom by MDMC and the trans is a stage V from RPM!:rofl: ED suggested the 2 stage and eboost do not know much about the eboost but i want multiple settings with ability to power up for track days. The car will start going back together monday now that all parts are in and Ed is going to track progress with pics along the way that I will post. So now what do you guys think I will hit HP and tq wise on street tune and strip tune? I am looking for 700-750 street and of course more with strip tune? Will post dyno results and also we are going to track tune car at IRP in Indy so we will also have times as we progress! Car has been apart for over 6 months and I can not wait to get it back!:willy: Also ED Potter has been around for awhile and I have heard great things about him. He is a great guy to work with and lives up to his great reputation.:thumbs: |

Earl
Honestly not for sure on the DP.
Thanks and I have seen alot of Fbodies making that HP with a 408 on a 76 turbo. But if a 88 is needed I will go that route.:cheers: |
Great! Post pics when done :thumbs:

Front mount or rear mount ? That turbo is on the small side for a 400+ cid motor , that's why I swapped my 76GTS for a Turbonetics ball bearing Y2K88 , the Y2K is a small frame 88 and is rated to 1400hp flywheel , the 76 is rated for a max of 1100 on the most effcient set up .

Turbo
It is a front mount kit. I posted pics a year ago when it was on my stock motor. Nice clean set up and as Ed works on car we will post pics. With my goals of 750hp street and maybe 850 strip It should be able (76mm) to do what I want but like i said if not a new unit is cheap compared to the total cost of what I will have in car.:eek:
Thanks |
Having 497rwhp on that motor is awesome!! My low CR 408ci motor made 430/440 and it hit 800rwhp EASILY w/the paxton on it. Making 700+rwhp w/the right turbo will be a 91oct. cake walk. Throw the big t88 on there and 1000rhwp is all yours if you can keep the heads clamped down and add a little 104+ or better octane in w/it. Good luck w/it and after all the chaos is said and done, it'll be worth it in the end!

Thanks and maybe I can finally use the CCW drag pack I bought from you that have been is storage for a year!:thumbs: |
:iagree: I hear a GT4718 screaming your name:rofl:
Im with the rest of the camp. With a motor that has that much base HP Id have a pair of 42R's on there. I have a similar motor in a camaro and the 4202r's are making positive pressure below 3K and hitting like a sledgehammer in the arse between 3 and 4k. A single T4 based 76 will have rootsblower like boost response, including part throttle boost. |
Thanks for all the kind words Tim! I can't wait to get this car to the track:thumbs:
The engine is a masterpeice built by the guys down at Grimes Automotive, I was super impressed with the no-boost dyno numbers, this thing will easily exceed Tim's goals at the track, but still be a nice streetable car that isn't too scary on the street, which is what he's looking for. The one-off MDMC single front mount kit is very nice, and features all stainless steel construction, and 3" down pipes, and a very large front mount custom intercooler. It was hand fabricated by John Lee, and is very nice work. We're using the best of everything, RPM Transmissions stg IV 4L60E, Yank converter & drive plate, DTE rear, Eboost2 controller with Synergy 2step and line lok I just got back from Florida, but I will get some pics posted soon, as long as it's OK with Tim, I would be happy to answer any questions.

Great!
Ed you can answer as many questions as you have time for and post pics. There is nothing secret about this project. We just want fast times!:D

I agree with what many have said about turbo sizing.. Since I am on the Supra Forum often I have seen a lot of new T4 turbo's in the 80mm to 81mm range that are very promising. If a 3.0L motor can hit 1000rwhp easily with a Sound Performance new 81mm T4 turbo you should be able to hit that easily with much less boost. I am not saying that it would be efficient, but I am saying it is doable.. If you get a chance have Ed P. take a look over in the SF and maybe SP can do something for you guys. SP is also working on a C6Z06 at this moment..

Thanks
Thanks for the info on the Supra Forum and I will have ED look at that. My Turbo is a T76 not a 76 GTS I am not sure what difference that makes but I think some. Thats why Ed is working on car and not me I just drive.:D

Going to see
Going to take Ed my new brake kit rotors, pads, lines and to see what the progress is. Should be running next week then street tuning and hopefully track tuning at IRP in Indianaplois!:D

Good to see you Saturday Tim. I have been taking some pics of the work, and will try to sit down and sort through them in the next couple days so I can post a few.
