BI-Performance

Our customer came to us wanting a little more from his 125K mile beast, as he already had the Kleeman 168mm crank pulley and K&N filters. We opted for the Kleeman Headers, and it just goes to show that these two mods make big power.

Tony did his thing, and we ended at 459rwhp/530rwtq. Everything else on the car is 100% bonestock, including cooling.

Enjoy

is that the man that picked up 40hp from the headers.

jddumas

Yes sir. I was at 420 before the headers.

Toadster

very nice - and on a 125k car!

hmm - so I could be around 490 with headers...

DVC

Great work guys! Stout numbers and great mods.

cij911

Reading comprehension could be your friend.....Car is ~460 whp with headers....

DVC

I think he means on a DJ. This dyno reads low on HP.

Toadster

yes, I'm 446 without headers... so add 40 - 486 (which is ~490) :p

yes DJ < Dynojet for readings so he'd be over 500 on a dynojet

cij911

Sorry, reading comprehension could be my friend....Karma is a byatch..

Generally Kleemans add ~20 - 30 whp and LT headers 40 - 60 + whp....

jddumas

I think you are exactly right about the typical hp gains. Not sure why I managed to get more. Maybe some of the guys with more knowledge can explain. All I know is I'm happy I went that route and happy with the job BIP did.

iv made almost 600whp on kleemann headers

kleemans with there down pipes and the first cats cut off and then have a shop fab the rest and you have a full blown long tube setup for half the cost.

+1 Stayed tuned for my dyno, BI is in the process of building a custom midsection to go with my Kleemann install. Will be interesting to see the gains vs. long tubes.

BI-Performance

Yes, we cut the cats and installed kleeman down pipes. The last time jddumas e55 was tuned, was during the spring when the temps were up about 20*. That could have attributed to some of the cold weather gain we saw this time.

Either way, with such minimal mods, she is a strong one

Good numbers using a dyno dynamics heart breaker dyno.

Interesting Tell us more....I'd like to see something custom made for Kleemans all the way back to after the resonators....like a complete stainless bolt on....I'd be all over that...

SPatykAMG

+1 about to buy a set myself, would love to see what bip does for the mid section

abhatti55

ASP is making a 168 for me now, in the meantime BI will be able to make the midsection. It is going to be similar to chawkins setup minus the electric cut outs(Maybe he can post a pic of it) it looks great. Basically everything factory is coming out, right after the Kleemanns will be an x-pipe then straight to the resonator. Probably gonna do an intercooler and split the cooling as well. Coming from stock, I think this may wake the car up a little.

saleen01

nice, id need something with 2 cats.

E55amg/FD3S

That's wishful thinking! Come out to the next EC dyno meet at Dito's hopefully in a few months. At least this time you will have a working I/C pump ;-)

Toadster

LOL - i meant on the Dynojet I used no sense comparing different dynos...

but that would be fun for another meet-up!

AMG E Power

u could possibly toad ! berti00 made 500whp on dynojet with kleemann headers and S/C pulley.

novae500

Nice numbers w Kleemanns pulley and headers!!!!
