Cobra Jet Manifold (for S650)

[DarkHorseTT]

Your 7.7 run was on a cold day. 5 Celsius is 41 degrees Fahrenheit. You can't really compare that to a run at almost 80 degrees Fahrenheit.

Rob, do you mean Rob Shoemaker? He put it in writing that it makes less power than stock?

I mean, Boschma's car was tuned by Shoemaker. (Boschma is the maker of that adapter you installed with the two throttle bodies).

I have not seen anywhere that it loses power compared to stock.

robvas posted the dyno curves above. But click on the link and read the caption under the dyno curves.

please send link on Boschma’s tune that Rob made

And Lund tuned Steeda's

fun fact, those tpi/lt1 throttle bodies were only 2x48mm

@DarkHorseTT

Are you still using stock camshafts?

 

[DarkHorseTT]

And Lund tuned Steeda's

maybe shall I go to Lund for tune? He made me ESS g3 Mach 1 very good

 

[DarkHorseTT]

Are you still using stock camshafts?

yes, stock cams

 

[robvas]

yes, stock cams

The Cobrajet is going to give you more usable RPM, not necessarily make more power at the stock RPM ranges. It may not make more power on stock cams (or if it does, just a tiny bit more near redline)

Do you have dyno charts of your car with both intakes?

2018 intake vs cobrajet but the idea is the same

No, I have only stock manifold 540whp
Today installed Cobra and ran to highway for better numbers

The stock intake performs really well, it’s not like the gen 1 coyotes, where we could slap a C.J. / mono and turn it up to 8500 rpm on E85 and see serious gains.

you really need to add cams to wake it up, but you’re basically gonna end up with “boost money” into a much slower N/A setup.

i would sell the intake and just run stock/E85 tune until you’re ready to add boost

No problem to buy R2 cams, the problem in Moscow is who will install them

but I think I will buy them as we have no choice

When we did the Boschma's Speed Shop dual throttle body, GSC cams, and cobra jet intake manifold, we increased around 50 hp and 11 ft-lb of tourque. This was also on a Lund tune.

if I install camshafts R2, can I use car for daily ride?

please send the link to buy cams and springs

And yes you can still daily drive the car.

but would it be comfortable? Not for drag only
thank You sir

 

[steedazach]

Yes it can compromise ride quality without a good tune. My suggestion is to get a daily tune and a race tune you could maybe switch between. Installing the cams without a tune could result in rougher / more choppy idle, and reduced low end torque. Just important than if / when you do this, to get a custom tune. Better to buy once cry once.
