Project Manual Typhoon 9 Sec

Recommended Posts

I haven't done a 9" conversion buddy, I am still running IRS (Mal Wood) albeit modified with billet shafts and inner & outer cage's from Albion.

No they are part of the full exhaust! Are the BF tail lights diferent? I haven't even noticed LOL.

First of all good luck on getting a Ten.

See you a making the power to get it there easily, did you make that power with the exhaust

the way it is currently or was that pre adding the split and extra muffler.

just asking as the split being well done could have been better with a weld on around

the the end of the larger pipe so you could have grinded it smooth for minute better flow.

Also the fact that the single splits into 2 would also hurt exhaust flow aswell the extra

bends in the flow path.

I have been thinking of adding a second outlet on the left on mine but only a fake,

just havn't been able to find any cannons that have a 3.5" internal diameter.

What internal diameter are the ones you have chose.

The other option I'm thinking about is to run a hot dog with a 4" dumpy exit with

fake dumpy other side. I have wanted to do this from the begining as never liked the

X-Force going from single 3.5" into a twim exit muffler.

As soon as I build my engine and do the driveshafts I will also be aiming

to get that first manual 10, just hope I can before you get there.

Good luck

All power runs have been achieved with the full exhaust and splits!!! The welding and filing you are suggesting have taken place I just do not have a photo of it at the moment!

As far as restrictive flow on my exhaust is concerned there isn't any, it is one of very few exhausts in the country that actually continues 4" over the diff, which then split into twin 3". It has 3 mufflers all in all, one 4 " magnaflow before the diff and twin 3.5" cannons with 4" tips to complete the setup! 6Boost spent one whole week on the exhaust it wasn't easy, the photo's do not do it justice, the result in flow is the best I have seen in the 5 to 6 years I have been involved with these cars!!

Spiko . What gasket r u using on the head ? and stud kit?

Hey Trav,

Standard Ford head gasket mate, & standard Ford studs!!!!

The only stud kit on the car is on the bottom end champ!

Sweet 4" over the diff, that would have taken some close fitting and time, I used a 3" magnaflow on a 351w TD Cortina I had years ago

after reading a comparsion on the 10 top mufflers at the time, they where like 3rd best overall best equal Flow & the cheapest.

Also produced a nice sweet sound at WOT with unattracting sound while cruising.

Car went very well and impressed lots.

Been thinking of also swapping the X-Force center for a Magnaflow but dont know if its the right move as my X-Force

system seems to be working quite well.

It would be good if I could find some CFM readings for the X-Force & Magnaflow Muffler.

So they didnt say u may blow a head gasket at 35 ? I want to spin mine to 40 but they want to re do the studs and do a bronze and o ring seal I wish they did this the first time and would have saved a fair bit but any way

Trav,

They did say I would be pushing the limit, the choice to go for it is mine, my turbo won't make any more substantial power after 36 or 37 and I believe that my top end will handle this boost for race tune only! (I have recently serviced the head, studs,valve springs & lifters for this tune).

Your turbo will continue to make power all the way to 42 or 45psi, so I believe like they suggest it will be more necessary and safe for your setup!

Hope this helps, when you began this build did you think you were going to consider that much boost?

Cheers

Spiro

Yer I wanted to go to 40 psi last time . But I dont think they want to go past 40 with the lifters . I only want to max it out once just to see how power it really has. I have the quote on how much it is going to cost for the new gasket set up but I'm not real sure having that good of a seal is a good or a bad thing with that much boost

You can get a dyno run to show whatever power you want to see, if that appeals to you, but on most non-hub dynos it will depend on how well strapped down the car is and ramp rate used.

Far more credible is a good mph in a run at the track at full weight. Don't worry to much about the time.

I know from experience, as for 3 years I copped a "dyno queen' tag. Believe me, a high speed run down the track is very exciting.

As for exhaust I was running a 4" into dual 3" over the diff in 2003, but that was not for big power, just 340-360rwkw. That was all just R&D to see the effect of changes (and for looks). The exhaust was too big for the power, but also in those days we didn't have the low restriction cats that are available now. Also, not all mufflers are created equal, and you get what you pay for. As power increases you want the least restrictive muffler possible. I put looks aside, and a few years ago went to a straight single pipe with 4" over the diff and a single low restriction muffler. Downside it is very loud, but I think in many ways it depends if the car is a daily driver, and how much noise you can take, AND if your wife is a passenger. I could probably pick up an estimated 30 rwkw by going to a screamer pipe as my wastegate is poorly integrated with the dump pipe, coming in at a 90 degrees angle.

I think you reach a point where you hit a brick wall with trying to screw more boost in. Just because your turbo might be able to provide more boost it doesn't mean that it will be able to be used efficiently in generating more power. By all means try it and see.

Yes I have to do the exhaust like yours . I cant help myself I just want to find out . Any it spiko thread will be good to see how much diff a few more psi makes to the car good luck hope it go's well :thumbsup:

Your experience and comments are alway's welcome Brian,

MPH is surely the way to go, however tuning, AFR's and torque is also as important so escaping the dyno is almost impossible, I have had my fair share of Hub dyno experience as you are aware, they do show more accurate and higher readings for obvious reasons.

As far as more boost and no power is concerend I am sure we will find out shortly (car will be tuned this coming week), this will also bring to light how well the exhaust flow's and all tests will be with the full system, I will make sure this is clearly visible on the results. This particular tune will be done on a diferent dyno as well for comparative purposes.

My front runners and slicks should be here before christmas so we will know these results in the not to distant future as well.

Cheers

Hi Brian, have managed to get your hands on the Nizpro Carbon Fibre plenum? If so, have you managed to do any testing or power runs with it? What are your thoughts on it??

what rpm does the car see ? higher rpm is higher road speed, and with a huge turbo power should still be hangin on at 7k ? huge cams and port work would help with this. anyways good luck looks sweeeeeet :)

Spiro,

I doubt much work has been done on increasing power issues on the upper side of 600rwkw; say 1000HP at crank.

Post compressor; intercooler restriction, piping size, throttle body, plenum size & runner size and head flow capability & cams all come into the equation.... then there's the exhaust. Then there's block rigidity and reliability.

It would be good, if you could measure reliability, the extra power generated per pound increase in boost, and see how much the increase reduces with boost increase, and when you hit the limit.

Thank Mic,

I have been down that path before, this was not required with my current combo, the turbo will run out of puff before any of these things become an issue! I spin the street tune to 6850 and the race tune to 7200 with no drama's, the engine has done over 60K with over 400+rwkw's at these rpm levels, and I might add that it is performing flawlessly! (For now)

On a different note I have another engine combo currently in the making, it will be ready for January 2010, it will spin to 9000rpm, it has solid roller, solid lifters & rockers, it will run an 88mm Precision Billet turbo, it will be dry sumped, and it will make 1000rwkw's!! And before you all ask me the same question YES it will be a street engine going in to the F6. I do not want to divulge any more at this stage and I will be starting a different thread about this after new years. I am busy focusing on this 10sec pass for now, surely you all understand!!

Cheers

Hey Brian,

I understand what you are trying to say, but surely by now you have known me long enough to agree that I am not playing game's? Let's just wait untill next week for the psi vs power test.

We will all know more when this is said and done! I will let you all know what the outcome is.

Cheers

Spiro
