Can one estimate the power given a list of bolt on mods?
 

I was curious how much horsepower my car makes since it is modified a bit. :confused:

It is the Euro 82 spec 3.3 with CIS

The turbo receipt says a K28 and the guy I bought the car from said the turbo was a K28 cheater, but this is what is under there...

I have B&B headers and a GHL exhaust.

K&N filter and an aftermarket intake box.

Tial F40 wastegate with a 1 bar spring

The engine is in very healthy condition.


... so the last owner said he thought it was around 340 whp. Given the mods, does that sound about right?

I'm thinking 375 at the crank.

So how much loss is typical through the transaxle?

I have heard 17%.

I could be wrong.

... well I hope you are wrong :o ... otherwise my car has a measly 311.25 horsepower at the rear wheels.

At least my rear tires should last a long time :confused:


I understand these are all just estimates and we could be on the money or off the wall.
If I get a bigger intercooler, that's worth a little bit of power, is it not?

Your setup shares some similarity to my current setup:
Euro Exhaust w/ RarlyL8 Muffler
"Custom" Air Filter Assembly
K27-7200
SC Cams
0.7bar Boost
B&B Intercooler

- My cams give me about what your headers would give you so for the sake of argument lets call that a wash.
- Your 1.0 Bar vs my 0.7 Bar boost is good for ~40HP or so.

Mine made 306HP to the rear wheels dynoed on a 100* day.
Given the extra boost I'd say the PO was about right on your power level.

Bigger intercooler will free up some power by cooling the intake change. Mine was completely heat soaked during the dyno runs so any help there was cancelled out.
