4000GT - MKIV Supra 1UZ turbo - update

[stevechumo]

Went back to dyno... 456WHP at 13.Xpsi... unopened motor.

Nice result!!! What is your fuel management system and what ECU are you running?

ECU is some POS Kiwi thing ;-)


In truth i am well impressed as few have reached these levels on stock internals and survived for long.

Just running a high quality New Zealand made Link G3 ECU...

The video quotes 331 whp, which one is correct ?
The top of the graph says 'flywheel hp' so it is an estimate at the flywheel ?

Nice V8 T Supra! So this is with the skinnier rods? think I read that right...

Dynapack allow to estimate flywheel power by using a TC factor over one. Mine is set to 1.0, meaning its WHP, no correction added. If I estimated enigne power at 15% loss, the TCF would be 1.15. But as you can see in this case TCF 1.0. Video also states that 331WHP is at 5psi. Latest tune at 456WHP is 13.xPSI. Cheers!

Hi, I just saw this post!
Beautiful car!
Great Project! Congrats...

 

[drifty325i]

Awesome !! thats some serious power. Makes my 280hp atw look lame lol

 

[4000GT]

Thanks mate... reasonably happy, car is fast... but like the idea of 600WHP

 

[JBrady]

456rwhp using a 15% loss = 536hp flywheel

That is HUGE power on the "skinny" rods.

Unless you have upgraded I believe you are on borrowed time. Hate to see that block, crank and possibly heads and/or turbo ruined when a rod(s) cycle to failure.

Great results especially with the crappy SC400/Soarer exhaust manifolds. Bet it pulls like a train. Do you have a weight for the car?

 

[JustenGT8]

Early 1UZ = fat rods...he's just confusing you with a different engine cover

 

[RedPhoenix]

You have inspired me Do you have pics of your manifolds off the car?

 

[4000GT]

Car is heavy... its a Supra afterall! The light car is the AE85 track car thats getting a cage as we speak

Umm headers are just the stock ones... not much to see! Here are some pics though.

 

[stevechumo]

What size is the downpipe? Is it a split or single pipe? It seems to fit in there so well.

 

[4000GT]

Downpipe is 3.5", with the twinscroll exhaust (twin wastegate) and 2" WG pipe.

... but like the idea of 600WHP

ha, i love that, you can never have enough power really, if you have 100, then you want 200 and so on, i have that disease too. so did you end up fitting those arp studs to run that 13 psi? gaskets ? nice work keep it up.

 

[4000GT]

Hey mate, no the engine is unopened. Stock gaskets and head studs etc.

I will put the ARP studs and cometic gaskets in once the head is ready to go on. The head is slightly decompressed, so I am hoping for a nice safe 16-18psi on 98. That should see me in the 600WHP range.

 

[4000GT]

Actually the boost peaks at 14psi, but it made the 456WHP just under that.
