Just actually watched the video, me and my mate were standing near you when you did the run. I think i have a photo somewhere

At traxx? Rainy day as well... Didn't plan on geting on the dyno but the friends wanted to play the "guess" game. Won myself a case of beer over that one

[minime68]

Thanks guys. Like I said before, me and my friend were impressed with the people and cars there. Everyone was friendly and the cars were super clean!

Cooper put together a go-pro video of the car rowing through the gears . Many thanks to him!

^^^^lol. I'd let it go for 40K

• *UPDATE***

So after blowing a stock piston to pieces (#6 Cylinder), I ended up doing a complete engine build. Here are some details:

-Factory LSA Block
-Ported LSA Heads
-Manley 416 Stroker Kit
-Monster Twin Disc Clutch (rated to 1100RWHP)
-Magnuson Heartbeat 2300
-Built by Tune Time Performance in New Jersey and installed by myself and some friends

Goal with this setup is to make a conservative 850+BHP at about .8 Bar since the old setup made 764. Anything after that would be bonus. As far as the new blower, I will be spinning it at 21,000rpms so it will be moving some air . Hopefully I can finish getting it mapped up in the coming weeks so I can hit the rollers and she what she is all about. Stay tuned for more info.

Here is a video of the first start back in Mid April. Since then I have put 1018 break-in miles on the car.

There are a couple 416s driving around with great results. The stroke is not that much bigger than stock so shouldn't be an issue. Right now, I am seeing a little increase in mpg range (1-2mpg). The cam was a custom grind spec'd by Tune Time performance specifically for my build and blower. I can prob find the exact specs somewhere in my emails. The heads were also hand ported by the same shop and flow ~350cfm.

Yea I am interested too so can hardly wait. I expect to see gains just nothing to Impressive. I rather not get my hopes up. Once I get this clutch situation sorted then I should be back in business

[minime68]

So I am really close to finishing up the tune and have been doing some WOT runs. The car pulls hard as expected with some minor kinks to work out. What I've noticed is that the Heartbeat Supercharger recovers very quickly at the end of runs. Cruising, I average IAT2 temps around 6-10* degrees Celsius higher than IAT1s. My redline is set at 6800rpm so in the end the blower is being spun at around 21600+rpms. Here is a quick log I did at about 80% throttle but my IATs were already high to begin with from consecutive runs.

What boost are you running and what IATs are you seeing?

16 pounds of boost right now ~ 1.1 bar. IATs normally end up at 145-150* on a 1-4 gear WOT run if I start at 100*. At the moment, I am pulling the plugs to re-gap them since I am experiencing spark blow out. I have NGK TR7ix's on the way so until then, I'll just hope these fix the issue.

One of my buddies in London has a full bolt on 2009 C63. It is quick he just ran 11.2@126 on a 75 shot of nitrous.

I forgot to mention, that is in degrees Fahrenheit.

wormus said:

Yes, means nothing really but I'm running 14psi with 120deg F after WOT which goes up on hot, sunny days. Heat soak in traffic is awful though which is why I'm thinking of getting an AC chiller, maybe a good option for you?

Those are good temps you have there. If I come to a standstill for longer the 3-4 minutes then the underhood temps just skyrocket. I looked into a chiller but don't want the added possibility of another component failing :/ Down the road, If I cannot combat the temps then meth with be the solution.

Only just seen this thread, and fk me thar is cool! I need something that outrageously powerful in my life.

Thanks! Hopefully we should have new dyno numbers soon to see how the build came out.

[minime68]

Quick update:

Did a dyno pull at Eurospec this weekend with a group. We made 670 to the wheels with 12 degrees timing. It was a rather hot day and inside the facility even hotter. Intake air temperatures were at about 46* C at the beginning of a pull and finishing off at about 60*.

I may have to make a visit to Surrey Rolling Road to get a better grip on what kind of power it really makes. An SVM r35 GTR that runs high nines and low 10s made 576whp right before me. A couple other cars were dynoe'd really low as well. Hopefully I can find some time soon to get it to Santa Pod and see what it can do down the strip.

That's still pretty good given the warm weather but those IATs sound a little high. I'd be pretty pleased with that, who did the tune for you? Is that on normal fuel?

Well I called SRR today to see i f I could get in soon but they are on holiday until 5 AUG. Normally, I'd see much lower IATs on the street but it was an oven in there. AS far as the tune, I'm doing it remotely with help from a friend in the states on 98RON. He wants to do a race map but im not going to spend 5 quid a litre for VP109.

We are indeed

Yes I would prefer to use the same dyno as before so I can see the gains better. Eurospec Dyno put me at 669.8rwhp but I expected a bit more. Right before my session there was an 850hp SVM GTR that made 570whp and a fully bolt on C63 AMG with 150 shot making 579rwhp. Numbers seemed off a bit so I want to get a second look from you guys .

[minime68]

It's been a while since I have posted updates on this thread so figured I'd add a few.

-ditched the supercharger and had a custom turbo kit built
-dynoed at 1155rwhp/1122ftlbs
-20 psi on E60
-twin Gen 2 precision turbo 6266s
-forged factory block
-ported factory heads

The car is ridiculously fun to drive now . Hopefully I can get it to Pod soon and see if I can crack 9s.

wormus said:

This is awesome, glad to hear the update When you say "forged factory block" and "ported factory heads", are those both LSA? If it is, mine's the same spec (Lignefelter CNC heads, factory block/crank, forged rods & pistons). Only real difference is the turbos so you've given me something to think about!

Correct, engine has not been upgraded specifically for this build. I am running the LSA block along with ported LSA heads. I did remove the head bolts and swapped studs in for more clamping force. I have about 5k miles on it with no major issues so far.

Very cool then, that's impressive.

Any thoughts on longevity? Seems a lot for an alloy block. How much incremental cost was it for the turbos, paperwork etc and finally, what's it like to drive? Arnie had about the same in his Monaro and said it was pretty much undrivable? Must be a handful!

You'd think I'm lying but it drives better than with the blower. I drove it up to England back in June with the whole family in tow. This was one month after the initial startup. The car drives surprisingly tame until it gets into boost.

As far as the longevity...who knows? I wont find out until something goes wrong. Turbo kit was around $13K but I sold the supercharger setup and recovered a bit of it.

What a fantastic car, just read this thread. You have put some work into this . Have you got any videos of the new setup with turbos?

Thanks man. Yea a lot of personal time into the car but it is a hobby and I enjoy it . I have a few videos up if you want to check them out.
