FARK! Look at that cherry red exhaust setup!!

Nice work Matt, I'm sure it'll be a hoot to drive!

[ONPSI]

Great result mate

[milkandoj]

Great power and nice pic mate!
It does show though that FP's rating of 47lb/min is inflated, or tested running 40psi with meth injection and reving to 9k or somthing!

How did you go with the injectors? did they bump up the fuel pressure to give you the headroom?

[Liberoz]

415 Hp at 24 psi. It now revs to 8k. = 309.46Kwts at the fly not bad

Nice!!

Baby turbo you have there!!

Good to see a engine dyno setup.. which shop does that?

[milkandoj]

Hope i didn't sound like i was being rude about the power, that's great!
I been slowly considering a new turbo, and looked at the 68hta. The american shops seem to rate the turbos at the absolute choke limit so its interesting to see what they do in a more comparable setup to what i would be using on the same turbo, than a water meth injected setup running insane boost.

NA Autosport in Brisbane, formally Neal Lowe. It ended up using about 120 Litres of fuel on the engine dyno and the engine had full warranty for this process. Runs a full cosworth engine program for the run in which they used to use for the Sierra Cosworth engines.

I wanted a turbo which was going to provide good power for the track and hill climb. Any bigger and in my opinion it would have impacted the cars ability to perform ideally.

No offence taken. I have hit my goal which is 200Kw at the wheels(assumed drivetrain loss) although the engine builder is assuming I will achieve closer to 247 Kw as he believes that I will have a 20% drive train loss. If I have a 35% loss that will get me the 200Kw I was hoping for.

He was extremely impressed with the FP exhaust manifold but had to machine the 68HTA out to gain the maximum benefit from it where the turbo bolts onto the manifold.

The big thing for me is longevity. I want this to be a 5-6 year engine and have no issues.

How much hp gain .. bro ..on engine dyno ..

:thumbsup:

Really like the attitude!! Engines are too damn expensive and time consuming to keep rebuilding every 3 months!!

[Evo-00x]

Good stuff. Just read through the entire thread and I admire how you've gotten straight into it and having some fun. 220-250kw atw will keep your engine happy for some time to come for sure

[Hypo]

Was at the track today and what a difference. Driving out of the last corner of lap onto the main straight I am having to apply opposite lock to keep it going in a straight line. Need to check out the rear suspension as it is dragging its rear under acceleration.

The car just keeps pulling.

Only failure was the brakes!!!

[DOUGMO]

Good work, they are Lot of fun with some grunt 

[milkandoj]

Any dyno figures? I'm interested in what the drive train loss is! Even though its just a number its good to see a rough comparison.

When are you hitting full boost now the motor is in the real world?

I was thinking if you use the rule that 1lb of airflow supports 9.5-10.5 hp , to make 415 hp, its flowing ~40-43lb at 22psi. That pretty good considering how quick these turbos are meant to spool.

[slo gsr]

love the spacer lol very nice looking car

[Dean]

So thumbs up for the 68HTA?

[K33P_UP]

So thumbs up for the 68HTA?

Forced Performance really know how to make a good turbo! I'm pretty sure the 68HTA is a bolt on replacement and outflows the 16 and 18g turbos (should outflow my 18g turbo) I dont know to much about them though.

What are you chasing with your car Dean?

This car will be awesome fun, nice work by the way!

Hey sweet build mate, good to see someone really using their car. Have you looked at Project MU brakes? Japanese pads they use them in everything V8 supercars, rally cars, drift cars, and now i believe they are using them in the Nascar. I just put a set in my street car (only for street and mild track use) and they are so much better than the RDA's that were in it. You can get them from Racer Industries down here on the coast. Speak to Marty 07 5591 8198. Heaps of full race ones to suit your application.

It was street driven to make sure all the mixtures where ok and everything came back aok. I will take it to a dyno day when one is on to get some figures.

I also dont have a boost gauge as one isn't required due to the Autronic having a boost cut and all set through out the rev range. So I can't really answer the full boost question.

The turbo feels like full boost around 3500ish though and pulls all the way to 7500 rpm.

So thumbs up for the 68HTA?

For value for money and what I was setting out to achieve yes.

Also chucked on the FP race manifold as well.

Trying to do a budget brake option. The Pagids and the RDAs are ok it appears it is the fluid and the cooling. If I can get that under control it should help things. Next ones to try is the Hawks I think.

Im a sucker for quick spool. Which usually means little power up top, but from what i've been reading, the 68HTA spools similar to a 16g (just a little bit later) but keeps hauling more and more as the revs rise.
Sounds like a great street turbo for our platforms, just wanted real life confirmation.

[EIII]

Nice work, you’re spot on.. These turbos just keep hauling all through the top end.

Using specific gravity of pump fuel mine is flowing 39lb/min of air at 20psi based on my 950cc FIC’s running at 55% duty in the top end.

Also mine hits 20psi at 3550rpm in a 4th gear pull.. How is your boost control? Does it hold all the way to redline?

What compression ratio are you running?


Glad you're happy, people don't give this turbo enough credit....
