Stock vs Intake/Header on Stock Tune

This setup made – 152.3 HP / 120.8FtLb

Peak gains of 11HP and 4FtLb.

For our second test we did a few stages of adding parts to see what they gain individually. We first put on an Invidia Header. The car made 152.3HP and 120.8 FtLb TQ. With the stock tune and Header/Intake, the car started picking up power at 3500rpm and slowly increased power over stock till it peaked at 7% or 11 HP over Stock. At 4300rpm the car gained 4% or 4 FtLb of torque. That’s not bad for just bolting on a header. It definitely leaves power on the table when running a header with no tune but you still see gains from the header itself. The car was running leaner under full throttle then the stock tune so we definitely don’t recommend doing Header/Intake without a tune.

Stock vs Intake/Header on JMA Tune

This setup made – 154.3HP / 124.1FtLb

Peak gains of 12.8HP and 12.7FtLb.

We then performed a custom tune with the Intake and Header. We were able to make 154.3 HP and 124.1 TQ. With our Stage 2 Tune we minimized the 4000rpm Torque Dip even more than our STG 1 Tune and gained 12% or 12.7 FtLb torque at 4300rpm and 9% or 12.8 HP at 7200rpm. We were able to increase the power by 7-10 HP from 3700 to 7800rpm. You can expect a 5+ HP increase in power on 93oct. Different headers can also increase/decrease power as some are better designed than others.

Stock vs Intake/Header/Front Pipe/ Over Pipe on JMA Tune

This setup made – 155.0 HP / 124.4FtLb

Peak gains of 13HP and 18.6FtLb.

Next we installed a Tomei Over Pipe and Invidia Front Pipe. With the addition of those parts we made 155 HP and 124.4 TQ. Power remained pretty much the same from about 4600rpm to 7800rpm but from 3500-4500rpm we saw a 3-5 HP increase over just the header. The max power increase remained about 9% or 13 HP at 7200rpm but torque increased to 18% or 18.6 FtLb at 4100rpm over stock. Again you can expect a 5+ HP increase with 93oct.

Different headers can also increase/decrease power as some are better designed than others.

Stock vs Intake/Header/Front Pipe/ Over Pipe on JMA Tune with E85

This setup made – 161.8HP / 129.3FtLb

Peak gains of 19.7HP and 23FtLb.

Average gains of 16.5HP.

For our final test we drained out all the 91oct and put some Corn in. Utilizing the RaceRom Flex Fuel Features on Ecutek, we tuned the car on E85. We were able to make 161.8 HP and 129.3 FtLb TQ. The 4000rpm torque dip is almost nonexistent. From 3500 to 7800 we are making 13-20 more Horsepower over stock and a peak of 14% or 19.7 HP at 7200rpm and 23% or 23 FtLb of torque at 4100prm.

Different headers can also increase/decrease power as some are better designed than others.

Edelbrock Supercharger vs Stock

This setup made – 231.7HP / 172.5 FtLb

Peak gains of 92HP and 67FtLb.

Average gains of 57HP

These are the typical gains you can expect with the Edelbrock Supercharger kit. The 4000rpm torque dip is completely gone. We love the roots style superchargers because you not only get large peak gains but you also get large gains over the whole powerband. You can expect to see an average gain of 57hp throughout the whole power band with gains ramping from the 57hp average at 5250, up to 90+hp by redline. Peak gains of 67% or 92hp at 7300 rpm and 66% or 67FtLb at 4000 rpm
