Talking New Tiger Head Flow Numbers

We have been working on these heads for a long while. We are shipping heads weekly.

They will be at the PRI show.

Here are the latest numbers that should be found on anyones flow bench.

TIGER HEAD FLOW SPECIFICATIONS Race Ready Fully Ported
Flow numbers (corrected) @ 28" using Superflow 600*

100 .200 .300 .400 .500 .600 .700 .800 .950
71 139 202 274 339 385 421 439 450.2
61 108 146 186 220 252 273 285 290

TIGER HEAD FLOW SPECIFICATIONS Race Ready Head Cnc Chamber/Bowl[CO
Flow numbers (corrected) @ 28" using Superflow 600*

100 .200 .300 .400 .500 .600 .700 .800 .900
75 138 212 282 341 384 402 414 422
45 86 124 166 204 233 251 253 267

**Due to the variances in flow benches numbers may not be exact. Some may be higher some may be lower standard or raised port numbers. There is no significant difference between the ports.

I tried to get the numbers to line up for a 1/2 hour. I hope you can make out the readings.

I found to either do it like Gach did or use underscores to space the numbers out. That's the only way I can get them to work out when laying them out horizontally. See you at PRI! Oh, by the way, nice numbers!

Bob C response on PY...

"
The Tiger Intake is at casting and will add to the heads. The CFM drop was only 7 cfm compared to others of 35 to 45 cfm drop. You may kill a good set of heads with a bad intake. A Victor intake will not do the heads any good.

I know this doesn't really address the "street" aspect but worth posting.

I think if you compare Langer's to Rex's Hp numbers vs their induction. The single 4 numbers are very impressive.

Handful of "street cars" I've seen on PY. Couple all aluminum deals too.

No problem. I think there would be more but it is tough for most guys to drop 6K on a set of heads when they think 2K is a lot of $$$. I have 0ver $3K in my HPs and never thought I'd spend that kind of money on heads. Now the Tigers don't seem that bad. LOL.
